About an inch long, this leaf-feeding pest is a long-haired, pale green or yellow caterpillar with a black stripe down its back. It feeds from inside the silken, web-like nests it builds at branch tips.

Life Cycle: White moths lay woolly egg masses on leaf undersides. After feeding, the caterpillars crawl down the trunk to pupae; pupate overwinter in litter or attached to tree bark. There are up to four generations a year.
