Often mistaken for tent caterpillars due to their similar nests, Webworms are a Fall pest that differs in appearance and behavior. Adult female moths lay hair-covered egg masses, full of hundreds of eggs, under leaves in the soil during the summer months.  Eggs generally hatch in 1 week and upon hatching, immediately create a web of protection around themselves and foliage they are consuming. During a 6 week period they complete their transformation into full grown caterpillars. You may find their silken web nests appearing in early Fall on deciduous tree branches. Throughout time, they expand their webs around new foliage on the branches to consume while being in complete protection from predators and parasites. These silken nests usually consist of caterpillars, partially eaten or dead leaves, and fecal matter. Once the Winter cold starts to set in, the caterpillars travel to protected areas such as in the leaves or bark crevices, and begin their final stage before adulthood as  pupae, overwintering in dark brown cocoons.
