Biology Fall webworm caterpillars feed on the foliage of a variety of trees and shrubs. Conspicuously hairy, they appear rusty tan with a dark, almost black, body color. Some populations have a lighter tan color phase. Large tents of this late-season pest become noticeable in late summer and early fall. Caterpillars are particularly fond of alder, cottonwood, walnut, and apple. They sometimes feed on apple fruit as well as foliage. |
