Caterpillar is the common name for the larvae of members of the order Lepidoptera (the insect order comprising butterflies and moths).As with most common names, the application of the word is arbitrary and the larvae of sawflies commonly are called caterpillars as well.aterpillars as a rule are voracious feeders and many of them are among the most serious of agricultural pests. In fact many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce, whereas the moths are obscure and do no direct harm.
