The unpaired dorsal plate of the eleventh segment, called the epiproct, is roughly the same length as or longer than the paraproct. This distinguishes them from larvae of the genus Tramea, where the epiproct is shorter than the paraproct. Furthermore, the mouth parts (palpus) have 12–14 bristles and thus fewer than P. hymenaea which has 15–18 bristles.
|
|
The genera Amegilla and Anthophora are monophylic, based on a series non- homoplasious traits. Additionally, Amegilla is strongly characterized by several autapomorphies, including a gonostylus, the male phallic organ, that is fused to the gonocoxite, or interior region of copulation, and a curved maxillary palpus with distinctive surrounding fringe. These traits when subjected to bootstrap analysis yielded 100% cladistic support.
|
|
The tip of the abdomen is quite variable and less blue in more Southerly distributions.Novelo-Gutiérrez, R. (2009). Description of the larva of Acanthagrion. Odonatologica, 38(4), 321-328 The larvae are distinguished from others of the same genus, by having 3 premental setae, 4 setae in the lip palpus and a caudal lamella 8 to 10 times longer than its widest part.
|
|
The primary function of the epigyne is to receive and direct the palpal organ of the male during copulation. The various specific forms of epigynes are correlated, in each case, with corresponding specific differences in the palpus of the male. This specialization prevents individuals of different species from mating. The epigyne covers or accompanies the openings of the spermathecae, which are pouches for receiving and retaining sperm.

|
Vespula austriaca is a member of the family Vespidae. The genera Vespula and Dolichovespula are thought to be closely related and are considered sister groups. Their similarities include absences of strong seta on third segment of labial palpus, smaller scutal lamella, and a characteristic twisted pedicel in embryonic nests. The Nearctic population formerly considered as belonging to austriaca has been recognized as a separate species, Vespula infernalis.

|
Macroglossum vidua is a moth of the family Sphingidae. It is known from north- eastern Papua New Guinea. The length of the forewings is about 22 mm. It is similar to Macroglossum glaucoptera, Macroglossum corythus luteata and Macroglossum sylvia, but recognisable by the dirty grey colour of the underside of the palpus, the greyish of the bases of the wing undersides and by the broad antemedian band of the forewing upperside.
|
|
The hindwings are pale brown. It "differs from the other European species of Hydriomena in the shorter palpus, the more angled or irregular markings between the subbasal line and the median space, dark subterminal band, nearly always interrupted by a white or pale spot in the middle, absence of black vein-streaks near the apex".Prout, L. B. 1912–16. Geometridae. In A. Seitz (ed.) The Macrolepidoptera of the World.

Comostolopsis subsimplex is a moth of the family Geometridae first described by Louis Beethoven Prout in 1913. This species was described from Madagascar. This species has a bright orange face, bright orange palpus, the wings rather bright green, slightly darker than in Comostolopsis simplex, the costal edge of forewing is extremely narrowly ochreous; both wings bear a dark red discal dot and golden-yellow fringes. The forewing have two wavy, whitish, transverse lines.
|
|
The palpus is white, shaded with brown scales and the thorax underside is brown, clayish in the middle. The abdomen underside is either tawny with a series of more or less confluent brown patches at each side, nearly all tawny or brown with three series of tawny patches. The forewing upperside has two oblique antemedian lines, the space between more or less filled up with black scaling. The hindwing upperside has a brownish black base.
|
|
It has a long and wide-looped peritreme, and the trochanter of the palpus lacks a seta. When pupae were removed from their cells, V. rindereri remained inside the cells. It has only been reported in colonies of A. koschevnikovi in Borneo and seems to be specific to that species, as it has yet to be observed crossing over to colonies of A. cerana, even when they live in the same apiary.

The pair of terga at the free end are trapezoid and more furrowed than the scutum and the carina in between are wide and forked. The tergal flaps are yellow, giving a coloured rim to the plates in the living animal. The body concealed by these plates consists of a head and thorax with a vestigial abdomen. The head bears the mouthparts consisting of a labrum with fine teeth on the inner margin, a blunt palpus, mandibles and maxillae.
|
|
In a study of 1000 freshly ejected T. penetrans eggs, it was found that females are generally smaller than males for all criteria. In some cases, though, females had a bigger epipharynx and maxillar palpus. Due to its burrowing activity, the chigoe flea has developed a well-developed lacinia and epipharynx that is used to penetrate the skin. Overall, the fleas’ head is relatively flattened, which again aids in burrowing through the epidermal and dermal layers.

Spiders perform cannibalism under a range of circumstances. Females eating males: Perhaps the most widely known example of cannibalism in spiders is when females cannibalise males before, during or after copulation. For example, the male Australian redback spider (Latrodectus hasselti) is killed by the female after he inserts his second palpus in the female's genital opening; in over 60% of matings, the female then eats the male. However, the theory of the "sacrificial male" may have become greater than the truth.
|
|
Throughout, the dancing male flicks his forelegs up and down, holding them wide apart at first and bringing them closer and closer together as he nears the female. Then, with forelegs held almost parallel before him, he touches the female cautiously once or twice. If the female remains still at this stage, the male climbs over her, and uses the forelegs to help turn her abdomen to the side. When the genital pore, which lies on the ventral abdomen, is thus exposed, the male inserts his palpus.

Thalassodes hyraria is a species of moth of the family Geometridae first described by Achille Guenée in 1857. It is found on Réunion in the Indian Ocean. Its holotype is in bad condition at the French National Museum of Natural History.Guillermet 2006: 284 Guenée also mentioned in his original description that the holotype was in bad shape, and that this species is similar to Thalassodes quadraria with the only notable difference that the front is green, and the last articles of the palpus is longer and white.

Isodemis is characterized by the labial palpus obliquely uprising almost as high as the upper edge of the eye. The forewing is dominantly yellowish brown or ochreous brown, the median fascia is interrupted or indistinct near the costal margin. The male genitalia have a hooked gnathos and the valva have a C-shaped plica, with numerous fine wrinkles between the plica and costa. The female genitalia usually have a ductus bursae with a cestum and the single dentate signum with a conspicuous globular process placed posteriorly in the corpus bursae.

However, the three species of North American black widows do not usually kill the male (although they have been known to do so). Males can sometimes even live in the web of a female for a while without being harmed in any way. The male Australian redback spider Latrodectus hasselti is killed by the female after he inserts his second palpus in the female genital opening; in over 60% of cases the female then eats the male. Although the male Latrodectus hasselti may sometimes die during mating without the female actually consuming him, this species represents a possible strategy of "male sacrifice".

In his original description, Lederer compares it to Crassa tinctella, of which it is about the same size. In his re-analysis Hering compares it to Scythris cuspidella, considering the genus Scythris the most closely resembling group to this odd moth, but remarks on the very different wing venation, the fore-wings having more and more pronounced veins, the hind-wings somewhat less but more pronounced veins, as well as differences in the genitalia. Meyrick mentions a resemblance to the genus Promalactis. The adults can be found with similar moths in the genus Pleurota in May in Turkey, but are said to be easily distinguished by the "naked and curved palpus labialis".

Descriptive terminology for head, thorax and forewing Wingvenation of Cosmopteryx lienigiella Cosmopterix species are very small to small moths with a forewing length of 2.9-6.5 mm. Head smooth- scaled, rather long and narrow caused by the large and bent scales on the vertex; frons distinctly lighter than vertex, from vertex to neck tufts often a median and/or two lateral white lines; antenna three-quarters to four-fifths of the length of forewing, often slightly serrate distally, and generally with a white, often partly interrupted, anterior line and several white sections in the apical part; labial palpus cylindrical, porrect, apical segment strongly angled upwards and often reaching well above the head. Thorax with or without a median white line, tegulae often lined white inwardly. Forewing narrowly lanceolate with long and very narrowly protruding apex and usually with a very characteristic yellow or orange fascia beyond the middle, this fascia bordered by tubercular metallic fasciae or spots; basal area with a metallic fascia or spots or with three to six longitudinal lines of different length, cilia concolorous around apex, paler towards dorsum.
