Males go through eight molts while females go through nine.
|
|
Here they undergo two successive molts to become sexually mature individuals.
|
|
Females typically exhibit 18 molts after the larval stages, while postlarval males molt about 20 times. Male blue crabs tend to grow broader and have more accentuated lateral spines than females. Growth and molting are profoundly influenced by temperature and food availability. Higher temperatures and greater food resources decrease the period of time between molts as well as the change in size during molts (molt increment).
|
|
The larva feeds on the host and molts to a nymph. The nymph is similar to the larva but has four pairs of legs. Then the nymph feeds and molts. This molt is either to the first of several more nymph stages, or to an adult.
|
|
The larvae that hatch (called phyllosoma larvae) do not resemble the adults. Instead, they are flat, transparent animals around long, but as thin as a sheet of paper. The larvae feed on plankton, and grow through ten molts into ten further larval stages, the last of which is around long. The full series of larval molts takes around 7 months, and when the last stage molts, it metamorphoses into the puerulus state, which is a juvenile form of the adult, though still transparent.
|
|
Molting may continue into adulthood, and there may be more than forty molts in the life of a thysanuran.
|
|
Mews were originally cages in which falcons were placed during their molts, periods when they mewed in a sickly fashion.
|
|
After feeding off and leaving its second host, N. reddelli molts once more. The nymph then feeds on a third host. This cycle is repeated for up to seven days, after which the nymph leaves its final host and molts to reach a sexually mature form. Mating and hatching of eggs occurs away from hosts.

He followed more than 1,200 caterpillars from the time they hatched, all the way through four molts and until they pupated.
|
|
Juveniles are pale white with no markings, but develop pigmentation after several molts. Egg sacs are pale cream or white in colour.

The adult form of G. ingluvicola resides in esophageal epithelium. From there it lays unembryonated eggs which pass to the feces, known as embryonation. The L1, now in the eggs which reside in feces, is ingested by an insect and molts twice taking it to an L3 stage. The L3 in the hemocoel is ingested by the animal and molts twice more.
|
|
The male crab, who is between molts, will select a premolt female who is expressing courtship behavior.Andrade, Luciana S; Fransozo, Vivian; Bertini, Giovana; Negreiros-Fransozo, Maria L; López-Greco, Laura S. The crabs communicate with one another through chemical, visual, and acoustic cues. The male then carries the female for thirty days in a precopulatory position under his body until the female molts.

|
Lifecyle of Ornithodoros soft tick Argasidae soft ticks have different lifecycles from Ixodidae hard ticks, and these are very variable between species. Typically, in Ornithodoros, a larva hatches from an egg laid in the nest or resting place of the host. The larva does not feed, but directly molts into the first nymph stage. This stage feeds, then molts into the next nymph stage.
|
|
As with other crustaceans, copepods have a larval form. For copepods, the egg hatches into a nauplius form, with a head and a tail but no true thorax or abdomen. The larva molts several times until it resembles the adult and then, after more molts, achieves adult development. The nauplius form is so different from the adult form that it was once thought to be a separate species.
|
|
The magnolia warbler undergoes multiple molts during its lifetime. The first molts begin while the young offspring are still living in the nest, while the rest take place on or near their breeding grounds. The warblers molt, breed, care for their offspring, and then migrate. Chicks hatch after a two-week incubation period, and can fledge from the nest after close to another two weeks when their feathers are more developed.

Dunn, J (2006) They are long, have a wingspan, and weigh .Floyd T (2008) They have 2 adult molts per year and a third molt in their first year.
|
|
Hemimetabolous insects, those with incomplete metamorphosis, change gradually by undergoing a series of molts. An insect molts when it outgrows its exoskeleton, which does not stretch and would otherwise restrict the insect's growth. The molting process begins as the insect's epidermis secretes a new epicuticle inside the old one. After this new epicuticle is secreted, the epidermis releases a mixture of enzymes that digests the endocuticle and thus detaches the old cuticle.
|
|
Three more molts occur, J2 becomes J3, J4 and then adult. M. incognita is sexually dimorphic. Females acquire a globose shaped body while males become vermiform and leave the roots.
|
|
Adulthood is reached for most species after several months and many molts. The lifespan of Phasmatodea varies by species, but ranges from a few months to up to three years.

They have two molts per year and a third molt in their first year. The call of the male is a short whistle; the female's call is a soft quack.
|
|
It is olive green with pale flecks and a mottled light and dark brown head. It builds leaf perches from the leaf midrib, like the larvae of other members of the genus. After nine days, it molts into the second instar which is green with various shades of brown and a light brown head. After eight days it molts again into the third instar which is a pale brownish yellow covered densely in yellowish conical tubercles.
|
|
When the eggs hatch, the female releases them by waving her tail in the water, setting batches of larvae free. The metanauplius of H. americanus is long, transparent, with large eyes and a long spine projecting from its head. It quickly molts, and the next three stages are similar, but larger. These molts take 10–20 days, during which the planktonic larvae are vulnerable to predation; only 1 in 1,000 is thought to survive to the juvenile stage.
|
|
After 10–12 hours, the eggs hatch into nauplius larvae, which are long, planktonic and unable to feed. They molt five times to reach the protozoa stage, long. These grow to long over two molts, before passing through three molts as a mysis larva. About 15–20 days after hatching, the animals reaches the postlarva stage; in the second postlarval stage, at a length of , they begin to enter estuaries and drop down to the substrate.
|
|
Larva molts, turn into a pupa, then young adult and finally mature adult. Ladybugs can come in all different sizes. Ladybugs look different. Some ladybugs can be red, orange, yellow or even black.
|
|
Hormonal IGRs typically work by mimicking or inhibiting the juvenile hormone (JH), one of the two major hormones involved in insect molting. IGRs can also inhibit the other hormone, ecdysone, large peaks of which trigger the insect to molt. If JH is present at the time of molting, the insect molts into a larger larval form; if absent, it molts into a pupa or adult. IGRs that mimic JH can produce premature molting of young immature stages, disrupting larval development.
|
|
At the end of the pupal stage, the pupae leave its protective shell and swim upwards to the surface. Upon reaching the top of the water it molts one final time into the adult stage.
|
|
Metacarcinus anthonyi reaches sexual maturity after 10–12 molts. Mating typically takes place in June, and occurs shortly after the females have molted. Before molting, females release a pheromone which induces courtship behavior in the males.
|
|
The tail is edged in white. The belly is grayish white. Sonoma chipmunks have 2 molts per year, having a summer and winter pelage. The winter pelage is generally slightly darker and duller than the summer pelage.
|
|
The larva feeds on the tissues of the gall and molts twice before excavating a narrow exit tunnel out of the gall in mid-September. After digging its tunnel, without actually opening up the gall to the outside, the larva overwinters and, if it survives, molts into an adult and leaves the gall the following spring. A number of predators and parasites prey on the larvae of E. solidaginis. The black-capped chickadee (Parus atricapillus) and the downy woodpecker (Picoides pubescens) target large galls, breaking them open and removing the larva living inside.
|
|
When a healthy bee finds its hibernation site, the 3rd stage larvae would infect the bee by penetrating it. The bee emerges to the surface during the spring season, and by that time the nematodes has developed into a mature female producing eggs within the bumblebee; 1st larvae stage. The eggs then hatches and molts into the 2nd larvae stage, which then rapidly molts into the 3rd larvae; the 3rd larvae stage is the infective stage for S. bombi. These 3rd stage larvae would be in the bee's hemocoel, midgut, and hindgut.

It's found by combat androids led by Weyland, who takes pity on it and brings it back with him. Once on board the human's ship, 6 slaughters the crew and molts into a Praetorian; implying it'll eventually become the new queen.
|
|
The female carries eggs in a brood pouch on its ventral side. G. lacustris in higher elevations were more likely to have fewer but larger eggs than those living at lower elevations. G. lacustris undergoes several molts and juveniles resemble the adult.
|
|
The strong odor is a defense against predators. They feed on a variety of plants. The caterpillar molts five times before entering the pupal stage. The bulbous chrysalis is pale green or jade green and emits a repulsive, ultrasonic sound when touched.
|
|
Females are born a beige color, which fades as it molts, while the male is a darker brown. This species produces sexually. The female will deposit the dark, circular eggs in moist soil. The eggs take from 12 to 14 months to hatch.
|
|
The skin often has blotches that enhance a camouflage effect. This fish has appendages around the mouth, and sometimes real algae and hydroids grow on its skin. This fish molts every 10 to 14 days, and can change colors after the molt.
|
|
This animal molts about twice a year, once during late summer, and again during the spring. It has a narrow head with a pointed nose, and whiskers. The eyes are small and well hidden. The primary senses used for hunting are hearing and smell.
|
|
Following this, the female cannot be kept or sold, and is commonly referred to as a "punch-tail" or as "v-notched". This notch remains for two molts of the lobster exoskeleton, providing harvest protection and continued breeding availability for up to five years.
|
|
A protonymph then molts into an adult. The whole lifeycle takes 7 to 16 days to complete. A minimum of 13 days is needed to go from egg to egg. The larva is the only stage that has three pairs of legs as opposed to four pairs.
|
|
A unique characteristic of the skull is the presence of especially large auditory bullae. X. spilosoma has two pelages and molts each year. Adults emerging from hibernation usually display thicker pelages, which are shed by the springtime. Juveniles tend to have darker pelages than their adult counterparts.
|
|
832 mg to 1.125 mg. Female T. gerstaeckeri lay more eggs when there are changing temperatures, but a higher percentage of eggs hatch if there is a constant temperature. Females lay eggs for the duration of their life. Next, T. gerstaeckeri goes through a series of molts.
|
|
The life cycle is typical of plant parasitic nematodes. This means that Globodera tabacum nematode has four juvenile stages, molts four times and then finally reaches adult stage. The duration of its life cycle is speculated to be temperature dependent. Hatching is often initiated by root exudate.
|
|
Eggs (nits) are laid on a hair shaft. Females will lay approximately 30 eggs during their 3–4 week life span. Eggs hatch after about a week and become nymphs, which look like smaller versions of the adults. The nymphs undergo three molts before becoming adults.
|
|
After four to 19 days the eggs hatch. Many predators target the eggs, including reptiles. During the larval stage, the mealworm feeds on vegetation and dead insects and molts between each larval stage, or instar (9 to 20 instars). After the final molt it becomes a pupa.

Plumages and molts of Brown Pelicans . Natural History Museum of Los Angeles County Contributions to Science, (402). Like all pelicans, it has a very long bill, measuring in length. The nominate subspecies in its breeding plumage has a white head with a yellowish wash on the crown.
|
|
After five molts, they are fully developed and ready to overwinter in leaf litter. Both the adults and their larvae are very harmful to crops.Economic Plants and their Diseases They feed on various grasses and grain plants (wheat, rye, barley and sometimes oats, corn and millet).
|
|
They can probably live for several years, which is quite long for a harvestman, with molts occurring only every several months. They have been shown to survive without food for up to 43 days (Rudolph, 1979). They prey on very small arthropods, preferring springtails over booklice.
|
|
The red ring nematode follows a typical plant parasitic life cycle, having 4 molts before becoming an adult. The whole life cycle lasts approximately ten days. The survival stage is the J3.Blair and Darling 1968 The dissemination of this nematode depends on its relationship with its vector.
|
|
There is a complex interaction between JH, the hormone ecdysone and vitellogenin. In the development stage, as long as there is enough JH, the ecdysone promotes larva-to-larva molts. With lower amounts of JH, ecdysone promotes pupation. Complete absence of JH results in formation of the adult.
|
|
On average, the clutch size is 3 eggs. They usually make their nest on the underside of banana trees or palm fronds. The nest is a hanging basket made from finely woven plant fibers, mainly from palm leaves. When fledglings become fully independent, they undergo pre-basic molts.
|
|
Larvae are legless and are initially pale after hatching from their egg, but will darken as they undergo molts. The rear end of the body has a projections that acts as a breathing tube for the larva. The eggs are white and may be laid singly or in clusters.
|
|
Their mother will kill prey for them. In their first year of life, spiderlings molt up to 8 times. Females usually molt about once a year after maturity and depending on how much the tarantula is fed, it will result in more frequent molts inevitably resulting in faster maturing.
|
|
R. flavipes also molts into nymphs, which are the precursors of winged adult termites called alates which are sexually mature. Nymphal termites are non terminal and can revert to the worker stage. These reverted nymphs are called pseudergates. Nymphs and workers can also develop into secondary and tertiary neotenic reproductives respectively.
|
|
These casings tend to be quite hard, and have been compared to adobe. Most fecal shields are bound with exuviae, the "skins" shed from the insect when it molts. Some shields, such as that of Cassida stigmatica, are entirely frass-free, made only of exuviae.Müller, C. and M. Hilker. (1999).
|
|
Chickadees molt once a year; no prenuptial molt occurs in the spring. The postjuvenal molt at the end of the first summer of life is partial, involving only the body feathers and wing coverts. Thereafter, the postnuptial molts at the end of each reproductive season are always complete, involving all feathers.
|
|
The hatched stage 2 juvenile, while migrating through and feeding on cells in the cortex, then completes 3 successive molts, and after the final molt, immature adult females and males emerge with gonads not yet fully developed. The complete life cycle takes one month from the egg to develop into an adult.
|
|
The pupa are around 4 x 2 mm. After undergoing three separate molts, the larvae pupate, then emerge as adults. If conditions are unfavorable, a cocooned flea can remain dormant for up to a year in the pupal phase. The adults are roughly 1.5 to 4 mm in length and are laterally flattened.
|
|
A protective covering of wax is produced by the first and second instars and the adult female. The male undergoes four molts before reaching the adult stage, which is legged, winged, and has antenna and eyes. The species Pinnaspis buxi is thought to be parthenogenic, as male scales have not been found.
|
|
Like other large raptors, feathers are molted at slow intervals in order to not inhibit food capture. Only relatively small portions of the flight feathers are molted each year. Molts occur more or less continuously, although it may pause in winter if food is in short supply.RSPB Handbook of British Birds (2014).
|
|
Spawning occurs in spring just under the soil surface and the nymphs appear in April. These grasshoppers undergo several molts. The nymphs have the appearance of the adults, their color varies from yellow to bright green and ocher and the wings are absent or small, as they are gradually developed after each molting.
|
|
These feathers grow back when the bird molts (roughly twice a year). Nails should be clipped every four months to prevent overgrowth and ensure comfortable perching. A domesticated parrotlet's diet typically consists of mixed grains or pellets. Mixed grain diets usually consist of white millet, sunflower seeds, and a variety of other seeds.
|
|
Like in most other true crabs, light and temperature are the main environmental factors that determine reproductive activity. The female releases her fertilized eggs in its abdomen. This species has a long planktonic larval phase. As the larva matures, it undergoes a series of molts that allow it to grow and reach maturity.
|
|
Xiphinema diversicadautum are amphimitic nematodes with males being as abundant as females. Eggs are laid singly in thin water layers in the soil and are not part of an egg mass. After the first-stage juvenile emerges from the egg there are 4 molts, all of which occur in the soil.Coiro, M.I., et al. 1999.
|
|
The females of this species lay their eggs in the soil near potential hosts. The first molt does not occur until 24–48 hours after hatching. The following molts occur in six-day intervals after, and complete a life-cycle within 22–27 days. However, a life cycle of several months has also been reported.
|
|
The nymph feeds at the same site or close by and molts where it feeds. It emerges from molt as either an adult female or male. The female's single large blood meal is converted into a batch of 2000 eggs. The males take several small meals of blood to support their repeated attempts at mating.
|
|
Young Phyllium bioculatum are about long, dark red in colour and have reflex immobility. The species molts 5–6 times in a lifetime. Females are heavy-bodied and flightless, and each lays about 500 eggs in a lifetime. The abdomen is narrower at the base, and the femur of the fore legs are dilated.
|
|
The nymphs feed within the vascular system of the small stems on the plant where the eggs were deposited. After several molts, the nymphs become adult glassy-winged sharpshooters. The glassy-winged sharpshooter feeds on a wide variety of plants. Scientists estimate the host plants for this sharpshooter include over 70 different plant species.
|
|
The female lays anywhere from 30 to 80 eggs on the leaves and flowers of toadflax plants. In one to two weeks the larva emerges from the egg and begins feeding. This caterpillar undergoes five molts during a one-month period. The first- stage larva is about 5 millimeters long and dark gray in color.
|
|
In 1959 Humphrey and Kenneth C. Parkes published an important paper on molts and plumages. In 1959 Humphrey conducted field studies in Haiti. He was a Guggenheim Fellow for the academic year 1959–1960. For the academic year 1960–1961 he studied birds in Argentina. For three months in late 1960 in Patagonia, he worked with Roger Tory Peterson.

|
Chitin synthesis inhibitors work by preventing the formation of chitin, a carbohydrate needed to form the insect's exoskeleton. With these inhibitors, an insect grows normally until it molts. The inhibitors prevent the new exoskeleton from forming properly, causing the insect to die. Death may be quick, or take up to several days depending on the insect.
|
|
After it hardens, the new shell fills with body tissue. Shell hardening occurs most quickly in low salinity water where high osmotic pressure allows the shell to become rigid soon after molting. Molting reflects only incremental growth, making age estimation difficult. For blue crabs, the number of molts in a lifetime is fixed at approximately 25.
|
|
It is thought that this characteristic may enhance the virulence of this fungus to first instar nymphs by growing so rapidly it can overcome multiple molts that E. decipiens nymphs undergo. The ability of these fungi to develop in high humidity and moderate temperature environments, in addition to their virulence, make them good potential microbial controls for E. decipiens.
|
|
Molts occur inward towards the body on the wing feathers. Tail molt may generally start with the middle tail feathers, proceeding posteriorly to the upper tail coverts, also starting with the median feathers on the scapulars.Henny, C. J., Olson, R. A., & Fleming, T. L. (1985). Breeding chronology, molt, and measurements of Accipiter hawks in northeastern Oregon.
|
|
Journal of Raptor Research, 39:378–385. Arrested molt has been recorded in the late nesting period, often pausing after the 3rd primary is molted. Molts tend to be halted especially when food supplies are down during the brooding stage, and may be resumed after the stress of feeding the brooding diminishes.Howell, S. N. G. (2010).
|
|
Each instar - the period between molts - generally takes about 4–10 days. There are five instars before cocooning. At the end of each instar, a small amount of silk is placed on the major vein of a leaf and the larva undergoes apolysis, then ecdysis (molting), leaving the old exoskeleton behind. Sometimes the shed exoskeleton is eaten.
|
|
Gypsy moth parasitoids have been widely studied, but they do not seem to have major effects on the population. Four species of parasitic flies prey on gypsy moth larva. Parasetigana silvestris and Exorista larvarum lays an egg on the gypsy moth larva. If that egg hatches before the gypsy moth larva molts, the fly larva will penetrate the host.
|
|
The Mexican fox squirrel has a grizzled brown back with a yellow to rufous underside, and a charcoal tail frosted with white. Two molts occur each year; the winter pelage is more rufous and the scrotum is often ringed with white.Thorington, R.W., Jr., Koprowski, J.L., Steele, M.A., and Whatton, J. (2012) Squirrels of the World. Johns Hopkins University Press, Baltimore, 472 pp.
|
|
At least 60 spiderlings emerge from an egg sac. Unusual for spiders, they are subsocial at this stage: they remain together for about a month, but do not cooperate in prey capture. The amount of cannibalism correlates with the amount of available food. E. atrica molts seven or eight times before reaching the immature adult state, and after a final molt reaches maturity.
|
|
The three distinct stages in their lifecycle are egg, nymph, and adult. Only adults are able to reproduce and have wings. Prolonged nymphal stages, along with additional molts, can sometimes occur in B. giganteus for a number of reasons. One hypothesis is that the absence jostling and mutual stimulation which are found often in colony life could slow the developmental process.
|
|
In other instances, lower temperatures and reduced humidity can lead to delayed maturation and an increase in the number of molts. This is a response by the insect to unfavourable habitat conditions and can also be seen as a predatory response. Their lifespans can last up to 20 months depending on habitat conditions and diet.Bidochka, M.J., St. Leger, R.J., and Roberts, D.W. 1997.
|
|
Adults that reach sexual maturity would then migrate en masse to shore areas in order to mate, lay eggs, and molt. Activities that would have made them more vulnerable to predators. This could also explain why the vast majority of fossils found in such sites are molts and not of actual animals. The same behavior can be seen in modern horseshoe crabs.
|
|
It molts twice a year. In its breeding plumage it has orangish-rust upper parts, gray head and underparts and a distinctive reddish cap. In non-breeding plumage, the cap is brown and the facial markings are less distinct. The song is a trill and the bird has a piercing flight call that can be heard while it is migrating at night.
|
|
As many as 30% of pups die during their first year, due in part to their early immobility on land.Juvenile harp seal—a "bedlamer."Around 13–14 months old, the pup molts again, becoming a "bedlamer". Juveniles molt several times, producing a "spotted harp", before the adults' harp-marked pelt fully emerges after several years (or not at all in females).
|
|
The first stage of nymphs transforms to the next nymph stage when it leaves the host and molts once more. These nymph stages can reach up to seven stages. After the last nymph stage, it leaves the host to molt into an adult. The adults can continue to feed on the host feeding quickly and detaching from the host after each blood meal.
|
|
An ecdysteroid is a type of steroid hormones in insects that are derived from enzymatic modification of cholesterol by p450 enzymes. This occurs by a mechanism similar to steroid synthesis in vertebrates. Ecdysone and 20-hydroxyecdysone regulate larval molts, onset of puparium formation, and metamorphosis. Being that these hormones are hydrophobic, they traverse lipid membranes and permeate the tissues of an organism.
|
|
A single female lays about 500 to 1,500 eggs during her life, which lasts about two to three months. Eggs hatch only under favorable conditions, such as adequate moisture and warm temperatures. Root knot nematode development begins inside the egg. After the completion of embryogenesis, the first-stage juvenile remains inside the egg until it molts into the second stage juvenile.
|
|
Very little information is known about the cryptic forest falcons breeding behavior. It is believed to nest in the wet season (December-May), as it molts remiges from April-August. This is also supported by possible damage from a nesting cavity in a female specimen collected in early June. It is presumed to breed in cavities as do other forest-falcons.
|
|
Onychodictyon sclerites appear to have molted with some specimens exhibiting perfectly conjoined plates from successive molts. Onychodictyon is represented by two species: O. ferox which has a pair of "antennae" on its "head" and a body with eleven pairs of legs; and O. gracilis which has a blunt front end without appendages and a body with twelve pairs of limbs.
|
|
The male then clings on to the female until she molts. The male releases its sperm into the female's marsupium, and the female releases up to 200 eggs. When the sea water becomes diluted, the eggs may swell up, to keep the total salinity around the embryos constant. They develop for four-and-a-half months, then hatch in the marsupium.
|
|
Males maintain small mating territories, few centimeters in size. When a female enters the territory, the male initiates a mating dance and eventually deposits a spermatophore, which is then picked up by the females. Fecundity is 20–40 eggs. The development from egg stage into maturity takes 10 to 24 months and involves three molts; molting may involve building a silk nest.
|
|
Eggs are laid singly in thin water layers in the soil and are not part of an egg mass. After the first-stage juvenile emerges from the egg there are 3 or 4 molts, all of which occur in the soil. Males can be abundant or sparse depending on the species, which may suggest the presence of both parthenogenic and amphimitic species.
|
|
Immediately after the egg hatches, the larva begins to make its own shelter by rolling a leaf blade with silk into the shape of a tube. It leaves the shelter to eat surrounding leaves. The caterpillar molts five times before it is ready to pupate. In between the molting the caterpillar makes a new shelter to accommodate for its growing size.
|
|
After the engorged larva molts to a nymph the remaining life-cycle comprises stages that are not parasitic, but free-living. There are several nymphal stages. The adults can be found crawling on vegetation, conspicuous with a dense covering of red setae (similar to hairs). Trombicula autumnalis, the harvest mite, causes severe pruritus to its host after it has detached.

The raptors of Europe and the Middle East: a handbook of field identification. London: T & AD Poyser. By their 2nd summer, the young eagles are still largely the same in colouring but tend to become more patchy below with increased heavy streaking. During the gradual further development through subsequent molts, the immature eagles develop a thicker subterminal band and a paler ground colour below.
|
|
The molts are rapid and the next stage remains in the hair coat to start feeding again. The combined feeding and molting periods take about 21 days. The engorged female drops from the host, hides under leaf litter on soil surface, lays one batch of eggs, and then dies. When eggs hatch, the larvae crawl up grass stems and wait until they can attach to passing cattle.
|
|
Females will molt approximately 7 times, with their terminal molts being in mid to late summer. Males will molt only 6 times and will have a terminal molt mid to late summer also. Nymphs and juveniles spend all spring and early summer catching as much prey as possible and growing. Adults reach sexual maturity in late summer and will mate as soon as they are sexually mature.

B. burgdorferi circulates between Ixodes ticks and a vertebrate host in an enzootic cycle. B. burgdorferi living in a tick can be passed to its offspring (Buhner, 2015). The spirochetes survive as the larvae molts into a nymph and persist in the nutrient-poor midgut as the nymph overwinters. Infected nymphs then transmit B. burgdorferi by feeding on another vertebrate to complete the cycle.

The nematode Heleidomermis magnapapula is a parasite of C. variipennis. The second stage juvenile H. magnapapula enters in the larval C. variipennis, develops, molts into an adult, and exits the host, killing the host as it exits. This parasitism of H. magnapapula and C. variipennis is commonly found in the Chino Basin in California Riverside County and the Allegheny, Thompson and Cayuga areas of New York.

Dynamic Ad., Nelspruit, South Africa: 132–134. They soon begin to develop their own round, waxy covers. The male scale insect develops similarly until after the second moult when it becomes oval and darker than the female, measuring about one millimetre in diameter with an eccentric cover. The adult male is a small, yellowish two-winged insect that emerges from under its elongated cover after four molts.

Only individuals three years or older will mate. A monogamous species, female emperor geese have a single mate throughout their life and only mate with any other male if their mate dies. The species molts from late July to early August and leaves its breeding grounds later than any other species. The emperor goose breeds on tundra, building its nests in areas or closer to the coast.

The eggs that the female lays on the dung hatch into larvae after 1–2 days, depending on temperature. The larvae quickly burrow into the dung for protection and feed on it. At 20 °C, larvae undergo three molts over five days, during which they grow exponentially. After growth, larvae spend another five days emptying their stomachs before pupation, where no additional body mass is gained.
|
|
During the pupal stage, the larval body breaks down as the imaginal disks grow and produce the adult body. This process is called complete metamorphosis. About 24 hours after fertilization, an egg hatches into a larva, which undergoes three molts taking about 5.5 to 6 days, after which it is called a pupa. The pupa metamorphoses into an adult fly, which takes about 3.5 to 4.5 days.

However, they are not exceptionally radiation-resistant compared to other insects, such as the fruit fly. The cockroach's ability to withstand radiation better than human beings can be explained through the cell cycle. Cells are most vulnerable to the effects of radiation when they are dividing. A cockroach's cells divide only once each time it molts, which is weekly at most in a juvenile roach.

Earwigs are found on all continents except Antarctica. Earwigs are mostly nocturnal and often hide in small, moist crevices during the day, and are active at night, feeding on a wide variety of insects and plants. Damage to foliage, flowers, and various crops is commonly blamed on earwigs, especially the common earwig Forficula auricularia. Earwigs have five molts in the year before they become adults.
|
|
The eggs hatch after about 4 months. Young insects mature after about 5–6 molts in 4 to 6 months. Life expectancy from hatching to the death is of about 2 years. They are nocturnal and they feed on a wide range of plants, mainly on leaves of Rosaceae species (blackberry, raspberry, wild rose, hawthorn, cherry, cotoneaster, etc.) but also on leaves of oak, beech, hazel, chestnut, eucalyptus, etc.

"Once a leg is lost, a recluse spider does not regenerate a new one with subsequent molts", unlike the huntsman spider that does regenerate autotomized legs. With each time that a leg is autotomized, the recluse "changes its gait to compensate for the loss." During travel, it stops naturally and periodically when renewing its internal hydraulic blood pressure that it, like most spiders, requires to renew strength in its legs.
|
|
Eggs are passed through the feces of an infected definitive host, usually a mammalian herbivore including rabbits, sheep, cattle, and rodents. Under certain environmental conditions, which include optimal temperature and humidity, larvae hatch from eggs after several days. Hatched rhabditiform larvae grow on vegetation or within soil. After 5 to 10 days, two molts (L1 & L2) have occurred and the parasite becomes a filariform (L3) larvae that is infectious.

As an arthropod, A. magnificus, is segmented and bilaterally symmetrical. The body of the shrimp contains a hard external skeleton called, exoskeleton, made of chitin which periodically molts by a process called ecdysis. A. magnificus, has a compressed body composed of a cephalothorax, containing a head and a thorax attached to an elongated abdomen. It has five pairs of pereiopods, two pair of antennae, a mandible, and three pairs of maxillipeds.
|
|
Salinity and disease also have subtle impacts on molting and growth rate. Molting occurs more rapidly in low salinity environments. The high osmotic pressure gradient causes water to quickly diffuse into a soft, recently molted blue crab's shell, allowing it to harden more quickly. The effects of diseases and parasites on growth and molting are less well understood, but in many cases have been observed to reduce growth between molts.
|
|
After laying the nits (eggs), the female glues each to a single hair on the host. After 5 to 8 days, the nits hatch from the egg as the larva push the covering of the nit open (the operculum) when parting from the egg. Females lay up to 100 nits at a time. There are three molts that occur, each nymph resembling the adult but with increasing size.
|
|
The most common host of Nothoaspis reddelli is the insectivorous bat Mormoops megalophylla. A member of the Argasidae family, N. reddelli, has a multi-host life cycle (feeding on two or more hosts), feeding off each host to reach adulthood. After hatching, the instar finds its first host to feed upon and grows into a larva. The larva molts and develops into a nymph, which finds the second host.
|
|
After mating a male cannot mate again until after 30 to 60 min allowing the production of another spermatophere. Eggs are laid in the fall, in a series of small holes drilled into the bark. After remaining dormant for the winter, the eggs hatch in the spring and the young tree crickets begin feeding on aphids. They may go through as many as twelve molts before reaching maturity around mid summer.
|
|
Now that the grub is firmly attached by both its tail and head to the tarantula, it begins to suck the juices out of the tarantula's body. As it feeds, the larva grows, rapidly engorging itself on the tarantula and darkening in color. As it grows, it molts several times, casting off its head capsule and body skin. After each molt, it resumes feeding, often through a new perforation.
|
|
The larvae are especially vulnerable to predatory ants for about the first three minutes after hatching. After shedding the provisional cuticle, the larvae climb up the nearest vertical object. They are born reddish in color, but transform to black within two hours. Despite its large size, T. eques has a relatively speedy rate of larval development, undergoing five nymphal molts to reach the adult stage in about 40 days.
|
|
After the engorged larva has completed feeding, it detaches from its stylostome feeding tube, drops to the ground, and molts to a nymph. The remaining lifecycle comprises the free-living nymph and adult stages predatory on other minute arthropods. The adults resemble spiders. They actively hunt amongst the ground-level debris layer of vegetation and are conspicuous by their red color and dense outer covering of fine setae, appearing like fur.

|
The axial lobe of Bumastus is also very broad in comparison to the pleural lobes. The cephalon (head segment) is very large and strongly convex. The facial sutures (the divisions by which the cephalon splits when the trilobite molts) is opisthoparian, with the suture ending along the hind cephalic margin. The genal angles of the cephalon - the edges where the lateral and rear margins of the cephalon meet - are rounded.

Life cycle of Pediculus humanus capitis, which is similar to the body louse. The location of the body louse eggs are different from the head louse eggs. The head louse will lay their eggs on hair follicles, whereas a body louse will lay their eggs in articles of clothes. This picture represents the louse from egg to adult and the process of going through three molts to achieve adulthood.

Of all common cockroach species, the American cockroach has the largest body size; molts 6–14 times (mostly 13 times) before metamorphosis; and has the longest lifecycle, up to about 700 days. It has an average length around and is about tall. They are reddish brown and have a yellowish margin on the pronotum, the body region behind the head. Immature cockroaches resemble adults except they are wingless.
|
|
A second function of its hook-lined antennae is an apparent grooming behavior, in which it drags the antennae across the setae of its swimming legs to dislodge debris. In the second main stage, after its first molt, it is simply called a "juvenile", because it is very similar to the adult, only smaller. It can swim just as efficiently as the adult. The larva molts eleven times before reaching adulthood.
|
|
Females are slightly smaller, with their head and body lengths measuring around , with their tails adding , and they weigh about . This species undergoes seasonal molts during the spring and autumn. The summer coat consists of gray to gray-brown fur with some light yellow, while the winter fur is more of a dark yellow with some brown. In both coats, the underbelly is pale yellow to creamy white.
|
|
The larvae have five instars, four molts. Then the insect makes a hole in the pod wall and comes out, making a cocoon in the ground. This take place when the pods become mature and the plants become dry (from the end of July and up to the first ten-day period of September). Young caterpillars (not fifth instar) that did not finish their feeding can diapause, but eventually they perish.
|
|
This species is monoecious and holocyclic. When a cyclical parthenogenesis occurs, aphids reproduce sexually in the autumn and produce an overwintering egg, deposited on buds and bark crevices of the host plant. In spring the newly hatched nymphs develop in about two to three weeks and at least three molts to wingless, 2-3 mm large Fundatrix. A fundatrix can produce up to 80 virgin young larvae of the next generation.
|
|
The nematode starts to swell and get a swollen shape as it molts through the juvenile stages until the adult stage. Many eggs will be produced by the female nematode, and released in a gelatinous mass. M. exigua lays its eggs under the epidermis, unlike M.coffeicola that lays them outside of the roots. The juveniles that came out in the gelatinous mass will hatch and find a new feeding site and restart the cycle.

|
Insect growth is constrained by the inelastic exoskeleton and development involves a series of molts. The immature stages often differ from the adults in structure, habit and habitat, and can include a passive pupal stage in those groups that undergo four-stage metamorphosis. Insects that undergo three-stage metamorphosis lack a pupal stage and adults develop through a series of nymphal stages."insect physiology" McGraw-Hill Encyclopedia of Science and Technology, Ch. 9, p.

RRN is sexually dimorphic, i.e. sexes are separate, and reproduction is amphimictic or bisexual; both sexes are required. Following fertilization, adult females lay oval-shaped eggs, mostly within the cortex, measuring 66–72 µm in length by 26–40 µm in width that hatch after 4 to 5 days while inside the root. There are 4 molts that occur throughout the RRN life cycle, the first of which occurs in the egg.

50 cent euro coin (diameter 24.25 mm) for size comparison Compared to many other praying mantises, the ghost mantis is a "miniature species" growing to only about long. It comes in various brownish shades from very dark brown (almost black) to greenish gray. An individual's colors change between molts and are also dependent on light and humidity levels. Phyllocrania paradoxa is camouflaged so as to appear as dead, dried-up leaf material. exotic-pets.co.

After undergoing several molts, they migrate to the coral reefs and live in holes or crevices. As they grow, they molt or shed their exoskeleton to make room for their larger bodies. As in other decapods, after molting, the new exoskeleton or shell is soft, and has to harden. During this time, the lobster is highly vulnerable to predation and as a result they are usually very retiring until the new exoskeleton hardens fully.
|
|
As an insect grows it molts, growing a new exoskeleton under its old one and then shedding the old one to allow the new one to swell to a new size and harden. IGRs prevent an insect from reaching maturity by interfering with the molting process. This in turn curbs infestations because immature insects cannot reproduce. Because these IGRs work by interfering with an insect's molting process, they kill insects more slowly than traditional insecticides.

Following the third larval stage, at which point they have become infective, they travel back to the proboscis of the mosquito via the haemocoel and enter another definitive host. If the mosquito is highly infected, multiple larvae can be transmitted in one blood meal. Humans are a dead-end host for D. tenuis; after the larva molts into an adult, it cannot reproduce. The worm may live subcutaneously for several months before it dies.

Specimen The female scale insect has a circular, brownish-red cover about 1.8 millimetres in diameter. It is firmly attached to the surface when the female is moulting or reproducing. The insect itself is visible through the cover and has an oval body which becomes kidney-shaped at the last instar stage. The female molts twice, exuding the material from which the cover is formed and developing a concentric ring in the center each time.
|
|
The eggs are laid on the ground, hatch, and the larvae wait for or actively seek a host (questing behavior). A larva feeds, detaches from its host, molts into a nymph when on the ground, and quests by crawling on the ground or waiting on vegetation. The nymph feeds and repeats the same process as the larva, but emerges having developed the anatomy of either an adult female or male. Adults quest similarly to nymphs.
|
|
On average, the larval development of E. mella lasts for 10 days. Larvae emerge from their eggs on the surface of their hosts, after which they burrow into the host for the remainder of their development. Delays in development occur when the host molts. If the host does not molt, larvae are able to develop within an average of 6.4 days, as opposed to an average of 12.9 days if the host does molt.

Parkes described numerous bird species and worked on a committee to standardize the English names of birds. He was also involved in a landmark paper that clarified the terminologies used in describing the molts and plumages of birds (Humphrey–Parkes terminology). He was also involved in the production of the humorous journal, the Auklet, which he edited and also contributed to. A compilation of its issues was published in 1983 as The Antic Alcid.

The life cycle occurs more rapidly at warmer temperatures, and more slowly at lower ones. Once the egg hatches, the larval form must take one blood meal per week as it completes each of its five to six molts. Once it completes the final molt, it will have reached the adult stage and can reproduce. Meals take several minutes to consume, and occur only under the correct conditions: darkness, warmth, and carbon dioxide.

|
Saccinobaculus is observed to have both sexual and asexual life cycles. Sexual reproduction only occurs around the time when the insect-host is molting and is triggered by hormones from the insect's prothoracic glands. About a week before the insect host molts, Saccinobaculus produces gametes from a haploid cell through a single mitotic division of the nucleus and cytoplasm. Immediately after the gametes are formed, they unite to begin the process of fertilization.

Currently, spectacled eiders occur along the coast of Alaska and easternmost Russia and into the Bering Sea. There are two breeding populations in Alaska and one in Russia. Historically there were more breeding individuals in Alaska but more recently the Russian population is much larger. Currently the United States population is an estimated 3,000-4,000 nesting pairs The spectacled eider molts at sea anywhere from 2 to 45 kilometers from the shore and north of 63°N.

Feather molts can make the wings look quite variable in shape with some individuals appearing rather longer and narrower winged than others. In flight, the tail appears long and broad but if pinched in can appear surprisingly narrow. This species tends to fly with powerful but loose shallow beats. When gliding, they do so often on flat wings with well-spread feathers and the carpals pressed slightly forward but more so when entering a fast glide.

Lifecycle of a typical one-host tick These ticks are adapted to the advantages of specialising to feed on cattle and with all the feeding stages occurring on one individual host in a rapid sequence. They also can survive by feeding on deer or some wild bovid hosts. Infestation starts when larvae on vegetation attach to a new host. When a larva feeds, it molts at the site where it feeds and emerges as a nymph.

Since Leidy discovered Trichonympha in 1877, the genus has been studied extensively. In the 1930s to 1960s Lemuel Cleveland dedicated a large part of his career to studying the inhabitants of wood roach and lower termite hindguts, including Trichonympha. A large part of what we know about Trichonympha today stems from the research done by Cleveland. He focused mainly on what happens to hindgut symbionts when their host molts, which directly impacts the lifecycle of Trichonympha.

For the later, females need to produce sons asexually. The same or other females can switch at any moment from asexual to sexual reproduction, but producing haploid eggs, which require fertilization by males. The sexual eggs are then deposited in an ephippium (plural: ephippia, a resting egg shell), which will sink into the bottom of the water body when the female molts her carapace. After a resting period, which can last several years, the resting stages hatches.
|
|
A female can lay up to 30 eggs, then dies at the end of a burrow. Upon hatching, the six-legged larvae migrate to the skin surface and then burrow into molting pouches, usually into hair follicles, where vesicles form (these are shorter and smaller than the adult burrows). After three to four days, the larvae molt, turning into eight-legged nymphs. This form molts a second time into slightly larger nymphs, before a final molt into adult mites.

|
Some Prairie Falcon individuals molt into adult plumage back and wing feathers that have a more gray tinge than their brown juvenile feathers. First year molts tend to be usually incomplete particularly in the "shoulder" region. If the individual's back and wing feathers have a gray tinge and there are several feathers on the upper wings (shoulder) with a subtle but distinctly different brown tinge, then the bird is a second year bird because it didn't fully molt.

Babesia species are spread through the saliva of a tick when it bites. Already at its nymphal stage, a tick bites into the skin for a blood meal. The tick, if not removed, stays attached for three to four days, with longer periods of feeding associated with a higher probability of acquiring the parasite. The parasite can survive in the tick as it molts through its various developmental stages, resulting in all tick stages being potentially infectious.

Mating in blue crab is a complex process that requires precise timing of mating at the time of the female's terminal molt. It generally occurs during the warmest months of the year. Prepubertal females migrate to the upper reaches of estuaries where males typically reside as adults. To ensure that a male can mate, he will actively seek a receptive female and guard her for up to 7 days until she molts, at which time insemination occurs.

|
Butterflies like the small heath typically undergo multiple stages of development called instars, through which the insect grows noticeably larger in size. The small heath typically goes through four instars and molts three times. The third instar signals a diapause in which the larva hibernates. By the end of the fourth instar, the small heath larvae are a leafy green color with a green stripe running along its back and stripes a lighter shade of green on its sides.

The large telolecithal eggs may resemble the segments of a raspberry, and a female carrying eggs is said to be "in berry". Since this period lasts 10–11 months, berried females can be found at any time of year. In the waters off New England, the eggs are typically laid in July or August, and hatch the following May or June. The developing embryo passes through several molts within the egg, before hatching as a metanauplius larva.

|
Phasmids have an impressive visual system that allows them to perceive significant detail even in dim conditions, which suits their typically nocturnal lifestyle. They are born equipped with tiny compound eyes with a limited number of facets. As phasmids grow through successive molts, the number of facets in each eye is increased along with the number of photoreceptor cells. The sensitivity of the adult eye is at least tenfold that of the nymph in its first instar (developmental stage).

Bachman's warbler molts over the summer into its fall plumage. For adult males, the fall plumage is nearly identical to the spring, with the only difference being that the forecrown changes from black to gray. First year males also resemble their spring plumage, but have an olive forecrown and duller yellow underparts. Adult females possess the same plumage, though it looks fresher in the fall, while first year females have an olive-yellow forehead and a dull eyering.

These nematodes have the general nematode life cycle with four juvenile stages keeping their vermiform shape throughout the entire life cycle except the egg stage. Any of the stages, except the egg and J1 which molts inside the egg, can infect the root. The nematodes get inside the roots and move throughout the root laying eggs individually in the root cortex and maybe a few in the soil. This particular species of Pratylenchus reproduces by parthenogenesis.

His cybernetic form during the events of the Prime series is referred to as Meta Ridley and incorporates various ballistic weapon systems. A robotic duplicate, known as Ridley Robot or Mecha Ridley, appears as the final boss in Zero Mission. In Metroid: Fusion, he appears in the form of . Metroid: Other M showcases Ridley's life cycle, beginning as a small creature named Little Birdie that molts into a reptilian Mystery Creature before molting again into his adult draconic form.

Symbion pandora can reproduce both asexually by budding and sexually. The sexual reproductive cycle is triggered when the host crustacean molts its skin in order to grow: a feeding stage buds a male, which attaches to another feeding stage and triggers it to bud a female, which it impregnates. The female is able to swim, and finds another host crustacean, where the larva in her develops. The female dies, and the larva escapes, spawning another feeding stage on the new host.

As they feed and grow, juvenile pin nematodes will go through a series of four molts, growing a new stylet and outer cuticle each time. When the fourth juvenile stage (J4 or preadult) is reached, the nematodes may enter a survival stage in which they are resistant to unfavorable conditions such as low soil moisture, extreme temperatures, and lack of food Rhoades, H.L. and M.B.

In the direct development, first-stage larvae (L1) transform into infective larvae (IL) via three molts. The indirect route results first in the development of free- living adults that mate; the female lays eggs, which hatch and then develop into IL. The direct route gives IL faster (three days) versus the indirect route (seven to 10 days). However, the indirect route results in an increase in the number of IL produced. Speed of development of IL is traded for increased numbers.

The mouth opens into a triradiate, muscular, sucking pharynx. The stylets are lost when the animal molts, and a new pair is secreted from a pair of glands that lie on either side of the mouth. The pharynx connects to a short esophagus, and then to an intestine that occupies much of the length of the body, which is the main site of digestion. The intestine opens, via a short rectum, to an anus located at the terminal end of the body.

During the course of the battle, the Dimension Tide is launched, but Godzilla survives the attack. Most of the Meganula are killed by both Godzilla and the Dimension Tide, but a few manage to drain off some of Godzilla's energy and return to the sewer. With the last of their strength, the Meganula inject Godzilla's energy into a huge, sleeping larva that is in a giant, pulsating cocoon. It molts and appears from the water as Megaguirus, the queen of the Meganula.

Chapter 3. PTTH also stimulates the corpora allata, a retrocerebral organ, to produce juvenile hormone, which prevents the development of adult characteristics during ecdysis. In holometabolous insects, molts between larval instars have a high level of juvenile hormone, the moult to the pupal stage has a low level of juvenile hormone, and the final, or imaginal, molt has no juvenile hormone present at all.Gullan, P.J. & Cranston, P.S. 6.3 Process and Control of Moulting in The Insects: An Outline of Entomology.

This is called the "wheel" position. Eggs are laid in water or on vegetation near water or wet places, and hatch to produce pronymphs which live off the nutrients that were in the egg. They then develop into instars with approximately 9–14 molts that are (in most species) voracious predators on other aquatic organisms, including small fishes. The nymphs grow and molt, usually in dusk or dawn, into the flying teneral immature adults, whose color is not yet developed.

Third stage dauer larva (resting stage) of Phasmarhabditis hermaphrodita Under conditions of stress such as crowding and high temperature, L2 larvae of some free living nematodes such as Caenorhabditis elegans can switch development to the so- called dauer larva state, instead of going the normal molts into a reproductive adult. These dauer larvae are a stress-resistant, non-feeding, long-lived stage, enabling the animals to survive harsh conditions. On return to favorable conditions, the animal resumes reproductive development from L3 stage onwards.

The fertilized cell contains all the nuclear and organellar materials from both gametes until the onset of meiosis, which occurs 24 hours after the insect-host molts and triggers the digestion of one flagellum and one centriole from one gamete and the axostyles of both gametes. After meiosis is complete, the remaining centriole duplicates producing new flagella and axostyles. In mitotic cell division, only the axostyle is digested and renewed. There are some subtle differences in sexual reproduction between Saccinobaculus species.

The genus Passerina is a group of birds in the cardinal family (Cardinalidae). Although not directly related to buntings in the family Emberizidae, they are sometimes known as the North American buntings (the North American Emberizidae are colloquially called "sparrows" although they are also not closely related to these birds). The males show vivid colors in the breeding season; the plumage of females and immature birds is duller. These birds go through two molts in a year; the males are generally less colorful in winter.

To reach the fourth stage – the post-larva – the larva undergoes metamorphosis, and subsequently shows a much greater resemblance to the adult lobster, is around long, and swims with its pleopods. At this stage, the lobster's claws are still relatively small so they rely primarily on tail-flip escapes if threatened. After the next molt, the lobster sinks to the ocean floor and adopts a benthic lifestyle. It molts more and more infrequently, from an initial rate of ten times per year to once every few years.

Juvenile Cuban stone crab The Florida stone crab loses its limbs easily to escape from predators or tight spaces, but their limbs will grow back. When a claw is broken such that the diaphragm at the body/claw joint is left intact, the wound will quickly heal itself and very little blood is lost. If, however, the claw is broken in the wrong place, more blood is lost and the crab's chances of survival are much lower. Each time the crab molts, the new claw grows larger.

Like all other members of Prorhinotermes, P. simplex lacks a true worker caste (meaning permanently sterile workers) and has a linear ontogenetical pathway with a single nymphal instar. Soldiers typically arise from the late larval stage in mature colonies and can be identified from their marked wing rudiments. Each of their two molts from larva to soldier adds an antennae segment, and they contain a lot of the chemicals (E)-1-nitropentadecene and (Z,E)-α-Farnesene. They make up from 7-22% of each colony's population.

The female Sacculina larva finds a crab and walks on it until she finds a joint. She then molts into a form called a kentrogon, which injects her soft body into the crab while its shell falls off. The Sacculina grows in the crab, emerging as a sac, known as an externa, on the underside of the crab's rear thorax, where the crab's eggs would be incubated. After this invasion of the Sacculina, the crab is now unable to perform the normal function of molting.

Transovarial and transstadial transmission of the Ixodes tick Transstadial transmission occurs when a pathogen remains with the vector from one life stage ("stadium") to the next. For example, the bacteria Borrelia burgdorferi, the causative agent for Lyme disease, infects the tick vector as a larva, and the infection is maintained when it molts to a nymph and later develops as an adult. This type of transmission is seen in other parasites like viruses or Rickettsia. In addition to ticks, mites are another common vector.
|
|
The larva then burrows into the mucosal lining of the small intestine, where it undergoes two additional molts. In this phase of their lifecycle, these worms cause the most damage to their hosts. They then re-enter the small intestine and develop into adults, where they live their lives out feeding on gut content and making a vast number of eggs that would then be excreted by a host and free to continue their lifecycle. If the animal is able to mount an immune response to the larvae, i.e.

Mating occurs only after the female has molted, and the female signals her readiness to molt by urinating on or near the antennae of the male. The female extrudes the eggs from her body several months later; however, they remain attached under her abdomen for three to five months until they hatch. Young crabs are free-swimming after hatching, and go through five larval stages before reaching maturity after about 10 molts or two years. Juvenile crabs develop in eelgrass beds and estuaries where salinity levels tend to be low.
|
|
It also has developing scoli (horn-like protrusions) each tipped with four to five black spines. The head is a pale green with four vertical brown stripes and also covered with tubercles. The fourth instar develops after four days and is a light reddish brown with greenish sides, yellowish tubercles, and fully developed scoli as well as new developing ones. It molts after nine days into the last instar which is olive green with brown undersides and legs, it is densely covered with yellowish tubercles (particularly at the bottom surfaces).

D. tenuis is introduced to the host (either a raccoon or, as in some rare cases, a human) as a larva when the vector, most commonly an Aedes or Anopheles mosquito, takes a blood meal and the parasite enters the host through the bite wound. Once inside the host, the larva molts into its final larval stage and then into an adult. As an adult it resides in the subcutaneous tissue of the host. These adults are able to live up to ten years within the tissue of the host.
|
|
The crab only molts at night or in night-like conditions due to the crab being extremely vulnerable to predators without the protection of its shell. If the crab is becoming too large for its shell and the sun is up, the crab releases a hormone from a gland located on one of its eye stalks called the x-organ. This hormone prevents the crab from molting from its shell until it finds a safe place to molt or it has become dark enough outside to molt in safety.

However, this white mottling then fades late into the 4th year and the plumage becomes less contrasting. Although sexual maturity is considered to be attained at 5 to 6 years of age, usually the fully white tail and the uniform pale head and neck are not obtained until the 8th year. Juveniles first molt in May/June until October/November at just over a year of age. Their 2nd molt is the following year in March or April, with two more subsequent molts usually beginning around this time for the next couple years.

Once the infective J1 egg is ingested, the bipolar plugs are digested and the J1 larvae hatch in the small intestine and cecum. The J1 larvae penetrate the mucosa via the crypts of Lieberkühn in the distal ileum, cecum, and colon. During the next 5 weeks, the larvae undergo four molts (J2, J3, J4, J5) to the adult stage within the mucosal layers. The adult’s thicker posterior third then emerges through the mucosal surface into the lumen, while the thin anterior two-thirds remains embedded in the mucosal layers.

Pratylenchus penetrans is a migratory nematode which means it moves from root to root and is also an endoparasite which means go into the roots. There are both female and male nematodes, with distinguishing differences being a spicule for the males and that males have a bent tail while females have a straight tail. They reproduce sexually, with the females laying single eggs in the root or soil. After embryonic development within the egg to the first stage juvenile (J1), the nematode molts to the second-stage juvenile (J2) and hatches from the egg.

The nematode then molts from the J2 to J3, J3 to J4, and finally J4 into an adult. J2, J3, J4, and adults all have a vermiform, worm- like shape, and can all invade the roots. Entry into the roots is accomplished by mechanical pressure and cutting action of the stylet of the nematode, usually just behind the root cap but may occur through other surfaces of the roots, rhizomes, or tubers. The nematode feeds on the cells within the root, usually until the cell lyses and cavities are formed.

The island fox molts once a year between August and November. Before the first molt pups are woolly and have a generally darker coat than adult foxes. A brown phase, with the grey and black fur of the body replaced by a sandy brown and a deeper brown, may occur in the San Clemente Island and San Nicolas Island populations. It is unclear if this is a true color phase, a change that occurs with age, or possibly a change that occurs because of interactions with Opuntia cactus spines that become embedded in the pelt.

This species is a kleptoparasite of Diadasia olivacea. They will perch alert outside the host nest and wait for the host to leave before entering for short visits of 20 seconds to inspect the nest, then on the last visit disappearing for 2 minutes to lay their own egg inside. Their eggs have a long incubation period compared to the host. Their first instar young does not feed, but dispatches the much larger host larva, and then molts to a second instar, and consumes the host's pollen provisions.

The caterpillar goes through five major distinct stages of growth, and after each one it molts. Each caterpillar, or instar, is larger than the previous after molting, as it eats and stores energy in the form of fat and nutrients to carry it through the nonfeeding pupal stage. Each instar lasts about 3 to 5 days, depending on various factors such as temperature and food availability. Fifth instar with the white spots visible on the prolegs The first instar caterpillar that emerges from the egg is pale green and translucent.

Northern short-tailed shrew This shrew has a total length of , of which is tail; and weighs . The species exhibits slight sexual dimorphism in size, with the male being slightly larger than the female. The dorsal fur is thick and velvety, and can be black, brownish black, or silvery gray, with the ventral fur being a bit lighter and grayer. The shrew molts from a summer coat which is shorter and paler than the winter pelage in October and November, and back again sometime in February through July.

Size ranges from about 1.5 m, 64 kg in the male Galapagos fur seal (also the smallest pinniped) to 2.5 m, 180 kg in the adult male New Zealand fur seal. Most fur seal pups are born with a black- brown coat that molts at 2–3 months, revealing a brown coat that typically gets darker with age. Some males and females within the same species have significant differences in appearance, further contributing to the sexual dimorphism. Females and juveniles often have a lighter colored coat overall or only on the chest, as seen in South American fur seals.

Sixspotted Fishing Spider The juvenile spiders look similar to adults but are smaller and they go through a series of molts within their lifetime to grow and reach adult size. While somewhat visually similar to D. striatus, this species is distinguished by its unique pattern of three pairs of dark sternal spots and several light spots on the abdominal dorsum. Males have a more apically rounded tibial apophysis that extends past the tibia apex. In females, the seminal valve of the copulatory apparatus can be found in the anterior half of the dorsal epigynous area with loose fertilization tubes.

Given an adequate supply of food, larvae pupate and weave silken cocoons after three larval stages. Within the cocoon, the larva molts for a final time and undergoes metamorphosis into the adult form. This can take just four days, but may take much longer under adverse conditions, and there follows a variable- length stage during which the pre-emergent adult awaits a suitable opportunity to emerge. Trigger factors for emergence include vibrations (including sound), heat (in warm-blooded hosts), and increased levels of carbon dioxide, all of which stimuli may indicate the presence of a suitable host.

Evolution This means that individuals tend to develop at the same rate through each instar stage. Each nymphal stage lasts 7–10 days and the water strider molts, shedding its old cuticle through a Y-shaped suture dorsal to the head and thorax. Nymphs are very similar to adults in behavior and diet, but are smaller (1 mm long), paler, and lack differentiation in tarsal and genital segments. It takes approximately 60 to 70 days for a water strider to reach adulthood, though this development rate has been found highly correlated to the water temperature the eggs are in.

All the species of Brachypelma that have been studied in detail live in burrows. These have a single entrance, a little larger than the spider, opening into a horizontal tunnel that usually leads to two chambers: one where it molts and one where it rests and consumes its prey. The entrance is blocked with material, such as soil and leaves, bound together by silk when the spider is inactive for significant length of time; otherwise the entrance is open with some silk visible. North American tarantulas like Brachypelma are "sit and wait" predators, seizing prey passing by the burrow entrance.

Throughout its life as a larva the saddleback caterpillar will go through a series of growths and molts. During the period between each molt the larvae is regarded as an instar to indicate its progression into adulthood. The first instar: Caterpillar larvae vary in size and are capable of being between 1.5-2.0mm in length. At this stage the hatchlings lacks its characteristic coloring and instead tends to be a translucent lime green with green or black tentacles and green protuberances along the skirt which lack the long spiny thorns that are seen in older larvae.
|
|
At this stage larvae will also begin to eat plant tissue and grow to be about 5-8mm in size. Late instar: Acharia stimulea is most known for its late instar stage where it is easily identifiable through its unique marking that has become more vibrant. As the anterior and posterior range from being a vibrant orange, brown, or dark purple the top of the body has turned into a more vibrant green. The caterpillars' green body with its characteristic “saddle”has also become well defined with its color having developed into a dark-orange or brown color with each of its molts.

If a male loses his larger claw, the smaller one will begin to grow larger and the lost claw will regenerate into a new (small) claw. For at least some species of fiddler crabs, however, the small claw remains small, while the larger claw regenerates over a period of several molts, being about half its former size after the first molt. The female fiddler carries her eggs in a mass on the underside of her body. She remains in her burrow during a two-week gestation period, after which she ventures out to release her eggs into the receding tide.

By then, some birds have not completed the molt of the feathers of the capital region and the helmsmen of the center of the tail and the internal secondary sprouts have only partially emerged from the pod. Virtually all individuals have completed their molts by mid-October. Birds do not begin their migration to wintering quarters until the two outer primary sprouts and the two inner or central rectrices have completed at least two-thirds of their development. Therefore, there is a correlation between molting, particularly replacement of the remies and rectrices, and fall migration in red-winged blackbirds.

Eclosion of Papilio dardanus After about five to seven instars, or molts, certain hormones, like PTTH, stimulate the production of ecdysone, which initiates insect molting. The larva starts to develop into the pupa: body parts specific to the larva, such as the abdominal prolegs, degenerate, while others such as the legs and wings undergo growth. After finding a suitable place, the animal sheds its last larval cuticle, revealing the pupal cuticle underneath. Depending on the species, the pupa may be covered in a silk cocoon, attached to different types of substrates, buried in the ground, or may not be covered at all.

The first stage to hatch from the egg, a six-legged larva, takes a blood meal from a host, and molts to the first nymphal stage. Unlike hard ticks, many soft ticks go through multiple nymphal stages, gradually increasing in size until the final molt to the adult stage. The lifecycle of the black-legged tick, commonly called the deer tick (Ixodes scapularis) comprises three growth stages: the larva, nymph and adult. Whereas B. burgdorferi is most associated with deer ticks and the white-footed mouse, B. afzelli is most frequently detected in rodent-feeding vector ticks, and B. garinii and B. valaisiana appear to be associated with birds.

Canadian and U.S. folklore holds that the relative amounts of brown and black hair on a larva indicate the severity of the coming winter. It is believed that if a Pyrrharctia isabella brown band is wide, winter weather will be mild, and if the brown band is narrow, the winter will be severe. In a variation of this story, the color of stripes predict the winter weather, with darker stripes indicating a harsher winter. In reality, hatchlings from the same clutch of eggs can display considerable variation in their color banding, and a larva's brown band tends to widen with age as it molts.

By about the 4th winter, as the birds enter their subadult plumage, the forefront of the eagle is often a rather patchy mix of sandy and darker adult- like feathers. During slow annual molts, the dark feathers expand initially from the throat and upper breast outward. Late into the subadult stage, the birds also start to develop a pale crown and nape but usually the rear body still more juvenile-like, such as the pale rump-band and crissum despite the otherwise darkening tail and wing feathers. The full adult plumage is attained at 5–6 years of age but some subadults are already breeding before this.

Unlike coastal acorn barnacles which have been widely studied, the development of a whale barnacle was first researched in 2006 with Coronula diadema collected from the fin of a beached humpback whale. Immediately after hatching, the newly born nauplius larvae molted and, after six molts, reached the cyprid stage, the last stage before maturity. Unlike other barnacles, the stage II and III nauplius had a pair of horns projecting from the head, and the eyes in stage IV were crescent shaped. The cyprid had circular eyes and, like other barnacles, had several oil cells in the head which probably acted as food reserves as cyprids do not feed.

In biology, a biofact is dead material of a once-living organism. In 1943, the protozoologist Bruno M. Klein of Vienna (1891–1968) coined the term in his article Biofakt und Artefakt in the microscopy journal Mikrokosmos, though at that time it was not adopted by the scientific community. Klein's concept of biofact stressed the dead materials produced by living organisms as sheaths, such as shells. The word "biofact" is now widely used in the zoo/aquarium world, but was first used by Lisbeth Bornhofft in 1993 in the Education Department at the New England Aquarium, Boston, to refer to preserved items such as animal bones, skins, molts and eggs.

The blister causes a very painful burning sensation as the worm emerges, and the sufferer will often immerse the affected limb in water to relieve the burning sensation. When a blister or open sore is submerged in water, the adult female releases hundreds of thousands of stage 1 guinea worm larvae, thereby contaminating the water. During the next few days, the female worm can release more larvae whenever it comes in contact with water, as it extends its posterior end through the hole in the host's skin. These larvae are eaten by copepods, and after two weeks (and two molts), the stage 3 larvae become infectious and, if not filtered from drinking water, will cause the cycle to repeat.

These special cells, called teratocytes, grow to become giant cells visible to the naked eye. The teratocytes secrete hormones which work in tandem with the virus and the wasp venom to arrest the development of the host. Following hatching in the caterpillar, the wasp larvae will undergo 2 molts inside the host caterpillar’s hemocoel and, after 12 to 16 days post oviposition, the 3rd instar wasp larvae will emerge from the caterpillar and spin cocoons from which the adult wasps fly about 4 to 8 days later. This insect has the shortest flagellated spermatozoa in animals, being 6.6 µm long (nucleus and flagellum), 8800 times shorter than the longest ones (Drosophila bifurca).

The first instar larvae begin life as parasites of leafhoppers in the family Cicadellidae and then move to the nests of meat ants, Iridomyrmex purpureus, where they complete their development by feeding on the ant larvae. Females of this species lay large numbers of eggs near the trails of the ants attending the leafhoppers. The first instar larva spins a pad of silk on the abdomen of the host beneath the wings, with a small sac at the anterior end to protect the larval head. Once the larva leaves the leafhopper, it builds an oval, flat cocoon where it molts into a broad, dorsoventrally flattened larva with a small head that can retract into the prothorax.

In most other snakes, the tail tip, or terminal spine, is cone-shaped, hardly any thicker than the rest of the skin, and is shed along with it at each successive molt. In this case, however, the end-scale, or "button", is much thicker and shaped like a bulb, with one or two annular constrictions to prevent it from falling off. Before each molt, a new button will have developed inside the last one and before the skin is shed off its body, the tip of new button shrinks, then loosening the shell of the previous one. This process continues so the succession of molts produces an appendage consisting of a number of interlocking segments that make an audible noise when vibrated.

Juveniles are similar to adults with a brown back, feathers with buffy tips and darker brown central streaks, greater coverts edged with white, and light streaking on breast and throat. noted that some birds, mainly in the eastern part of their range, tend to be more rufous above, slightly buffier below, and have plainer tails with less obvious shaft streaks and barring on the central rectrices. Although rarer, even in the eastern part of the range, the rufous morph has been observed as far away as the Farallon Islands off California.J. Dunning personal communication cited by reports on an unusual sequence of molts and plumages in Cassin's and Bachman's sparrows – replacement of all pennaceous body plumage twice within a bird's first six months of age, and a gradual molt of body feathers in adults throughout the breeding season.

As parasites, they lack a pollen- carrying scopa, and are often extraordinarily wasp-like in appearance. All known species share the behavioral trait of females entering host nests when the host is absent, and inserting their eggs into the wall of the host cell; the larval parasite emerges later, after the cell has been closed by the host female, and kills the host larva. The first-instar larvae of nomadines are specially adapted for this, and possess long mandibles they use to kill the host larva, though these mandibles are lost as soon as the larva molts to the second instar, at which point it simply feeds on the pollen/nectar provisions. Another unusual behavioral habit seen in adults of various genera is they frequently "sleep" while grasping onto plant stems or leaves with only their mandibles.
