Caterpillars are the larvae of moths and butterflies. Caterpillars can be smooth, hairy or spiky.
While their winged adult forms are sometimes beneficial to flowers and gardens by aiding in pollination, the worm-like larvae can be a serious pest. Caterpillars can damage plants by chewing on the soft and succulent leaves, flowers and shoots and fruits of plants, and by boring into trees and shrubs (see Tree Borers). As they progress through their development and become larger, Caterpillars can cause increasing damage, up to the point of eating entire leaves.
Caterpillars are found throughout the United States.
