Caterpillars are the larval form of a member of the order Lepidoptera (the insect order comprising butterflies and moths). They are mostly phytophagous in food habit, with some species being entomophagous. Caterpillars are voracious feeders and many of them are considered pests in agriculture. Many moth species are better known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce.
The etymological origins of the word are from the early 1500s, from Middle English catirpel, catirpeller, probably an alteration of Old North French catepelose : cate, cat (from Latin cattus) + pelose, hairy (from Latin pilōsus).
