Caterpillars of most species eat plant material (often leaves), but not all; some (about 1%) eat insects, and some are even cannibalistic. Some feed on other animal products. For example, clothes moths feed on wool, and horn moths feed on the hooves and horns of dead ungulates.
In specific local subpopulations (studied in Wisconsin, Ohio, and Florida), it was found that eastern giant swallowtail caterpillars do better on their local host plant than on other giant swallowtail host plants. The local host caused the larva to develop faster than other plants that were also edible to the larva.
Cynanchum laeve is a food plant of caterpillars of monarch butterflies. [4] [14] Larvae of Euchaetes egle, the milkweed tussock moth, both in the Eastern and Western United States consume C. laeve. The larvae of these moths eat Cynanchum laeve and other plants when developing. [5]
In early instars, the larvae feed together in groups, but beginning in the third or fourth instar the caterpillars begin to feed individually. [8] [9] The larvae eat the entire leaf blade and are capable of consuming a few leaves each. Thus, large populations of greenstriped mapleworms are capable of defoliating trees.
The caterpillar feeds on trees in the willow family Salicaceae, including willows (Salix), and poplars and cottonwoods . The caterpillars sequester the salicylic acid in their bodies, which makes them bitter, and upsets predators' stomachs. As further protection, the caterpillars, as well as their chrysalis stage, resemble bird droppings. [7]

The larvae (or caterpillars) emerge in April and initially eat the buds of oak trees and young leaves inside them. [1] [6] When fully grown, the larvae are between 25 and 29 millimetres (0.98 and 1.14 in) long with a body that can be yellow-green or darker shades of green.
