Life History: North American population is parthenogenic (females reproducing by laying viable eggs not fertilized by a male). Eggs are layed in discarded bag in early spring soon after adult emerges from pupa and bag. Adult lives only a few days and does not eat. Caterpillars eat and grow till fall, then find a place (often seen on the sides of buildings) to spend the winter without pupating. In very early spring, as temperatures rise to a degree or two above freezing, the caterpillar pupates.
