Tent Structure
Fall webworm caterpillars incorporate leaves, and sometimes entire branches in silken tents spun, typically, at branch tips. (In contrast, eastern tent caterpillar, Malacosoma americanum, typically builds tents in the crotches of trees.) Fall webworm larvae develop and feed within these weblike tents. Tents contain feeder leaves, leaf fragments, caterpillar droppings, and cast skins.
Feeding Habits
Fall webworms feed on about 120 species of hardwood trees. Common hosts include pecan, hickory, walnut, elm, poplar, willow, cottonwood, and sweetgum.
