Caterpillar, larval stage of butterflies and moths, members of the order Lepidoptera, and corresponding in this special order to the grub, maggot, or larva phase in the life history of other insects. The caterpillar develops like any other larva from the segmented egg and differentiating embryo and undergoes several moltings, or ecdyses. It later falls into a quiescent pupa stage, and the pupa is usually sheathed in a silken cocoon.
