After about 35 days and 4 moltings, the caterpillars are 10,000 times heavier than when hatched and are ready to begin spinning a cocoon.

A common behavior for S. ocreata spiders is self-amputation in order to regenerate a damaged limb. However, the spiders that had regenerating legs needed about an additional 3.7 days to molt. Although the spiders that had regenerating legs need additional time to molt, when talking about the number of additional moltings that are needed, these spiders usually only need one more molting.

They gain a new pair with the first molting, and two pairs with each of their five subsequent moltings. Adults with 15 pairs of legs retain that number through three more molting stages (sequence 4-5-7-9-11-13-15-15-15-15 pairs). House centipedes live anywhere from three to seven years, depending on the environment. They can start breeding in their third year.

Silk moths lay eggs on specially prepared paper. The eggs hatch and the caterpillars (silkworms) are fed on fresh mulberry leaves. After about 35 days and 4 moltings, the caterpillars are 10,000 times heavier than when hatched and are ready to begin spinning a cocoon. A straw frame is placed over the tray of caterpillars, and each caterpillar begins spinning a cocoon by moving its head in a pattern.

The nymphs resemble fully grown adults except for size and the absence of wings. Nymphs usually undergo four to five successive stages of moltings (ecdysis), increasing in size and becoming more adult-like with each stage until the final molting. The stages are individually known as instars, with the earliest stage (just after hatching) being known as the first nymphal instar. Nymphs may also differ significantly from adults in colors and patterns exhibited.

Research shows that there was much variation in the number of instars, the time for development, the width of the cephalothorax, and the mass varied with different dietary patterns. Instars refer to the phases between two molting periods when an invertebrate animal develops into sexual maturity. The females that were well-fed actually needed more moltings to become sexually mature, needed less time for sexual development, and were found to be heavier than those that were starved long-term.

38 No. (Supplement 1) 2010Nurcan Özyurt, Selami Candan & Zekiye Suludere: The morphology and histology of the male reproductive system in Apodiphus amygdali (Germar, 1817) (Hemiptera: Heteroptera: Pentatomidae) Life: The Excitement of Biology 2(1) They have two generations a year, the first at the end of June and the second at mid-August. Adults of this second generation over winter from October to May. The fertilized females lay on the underside of the leaves masses of eleven to fifteen eggs, which take two to five days to hatch. Nymphs pass through five moltings.

Adult wasps lay their eggs in tobacco hornworm (Manduca sexta) larvae in their 2nd or 3rd instar (each instar is a stage between moltings, i.e. the second instar is the life stage after the first molt and before the second molting) and at the same time injects symbiotic viruses into the hemocoel of the host along with some venom. The viruses knock down the internal defensive responses of the hornworm. The eggs hatch in the host hemocoel within two to three days and simultaneously release special cells from the egg's serosa.

The female Stylops melittae gives birth to a large number of motile primary larvae, that are strewn upon blossoms. From there they can be delivered along with the pollen at the nest construction of the sand bees for which the species is specialized. In the nest construction the primary larvae penetrate into the host larvae and molt into exclusively endoparasitic secondary larvae. These roam about feeding in the host, and after a few further moltings establish themselves in the abdomen, and with their anterior portion break through between two abdominal segments of the host's skin, where they pupate. The exit point lays mostly between the 4th and 5th, more rarely between the 3rd and 4th, abdominal segment. There are substantially more females (77–92%) than males (2–23%).
