Prolegs of lepidopteran larvae have a small circle of gripping hooks, called "crochets". The arrangement of the crochets can be helpful in identification to family level. [3] Although the point has been debated, prolegs are not widely regarded as true legs, derived from the primitive uniramous limbs. Certainly in their morphology they are not ...
The thoracic legs are known as true legs and the abdominal legs are called prolegs. [64] The true legs vary little in the Lepidoptera except for reduction in certain leaf-miners and elongation in the family Notodontidae. [59]: 114 The prolegs contain a number of small hooks on the tip, which are known as crochets. The families of Lepidoptera ...
Lepidoptera (/ ˌ l ɛ p ɪ ˈ d ɒ p t ər ə / LEP-ih-DOP-tər-ə) or lepidopterans is an order of winged insects which includes butterflies and moths.About 180,000 species of the Lepidoptera have been described, representing 10% of the total described species of living organisms, [1] [2] making it the second largest insect order (behind Coleoptera) with 126 families [3] and 46 superfamilies ...
However, several morphological differences can distinguish the two: while both larvae share three pairs of thoracic legs and an apical pair of abdominal prolegs, lepidopteran caterpillars have four pairs of prolegs on abdominal segments 3–6 while sawfly larvae have five pairs of prolegs located on abdominal segments 2–6; crochets are ...
However while these larvae superficially resemble caterpillars, they can be distinguished by the presence of prolegs on every abdominal segment, an absence of crochets or hooks on the prolegs (these are present on lepidopteran caterpillars), one pair of prominent ocelli on the head capsule, and an absence of the upside-down Y-shaped suture on ...
This glossary of entomology describes terms used in the formal study of insect species by entomologists.. When present, elytra of the Staphylinidae are markedly abbreviate. This fly in the genus Scaptomyza has clearly visible rows of para-sagittal acrostichal bristles on its thorax the alitrunk of aculeate Hymenoptera comprises the three thoracic segments, plus the propodeum, which strictly ...
A Lepidoptera specimen drawer in a museum collection in Poland Another Lepidoptera specimen drawer in a museum collection in Poland. Lepidopterology (from Ancient Greek λεπίδος (lepídos) 'scale' πτερόν (pterón) 'wing' and -λογία [1]) is a branch of entomology concerning the scientific study of moths and the two superfamilies of butterflies.
Urodidae, whose species are commonly known as false burnet moths, is a family of moths in the lepidopteran order. It is the type genus in the superfamily , Urodoidea, with three genera, one of which, Wockia , occurs in Europe.
