The larva is covered with urticating hairs. People can get severe skin irritations should they come in contact with this caterpillar. The larval stage lasts for nine months, from August through June. Hibernates as a small larva in a tough communal web on a the food plant.


In autumn, the small caterpillars form colonies of larvae in trees and bushes constructed from a single leaf wrapped tightly with large amounts of white silk, which make a tough communal web. In spring, they emerge from the cocoon and grow into large caterpillars. By the end of June, the full-grown larvae start to pupate and the imago emerges towards the end of July. The adults come to light.
