Larvae The larvae of Lepidoptera are usually eruciform,with a well-developed head and a cylindrical body of 13 segments (3 thoracic and 10 abdominal). ■ A caterpillar is the larval form of a lepidopteran ■ Caterpillars have long segmented bodies and many sets of "legs".They eat leaves voraciously,grow rapidly,shed their skins generally four or five times, and eventually pupate into an adult form

Crochets ■ Crochets are small hook-like structures associated with prolegs that are found on the abdomen of immature butterflies/moths;i.e.,caterpillars.Prolegs are not true legs because they are non-jointed and are found only in association with the abdomen and not the thorax. ■ Prolegs and the attached crochets are used for grasping the substrate while a caterpillar walks or feeds. The presence of true crochets is an important identifying character for an immature butterfly/moth
