Diet

Caterpillar hosts: Various trees and shrubs including box elder (Acer negundo), sugar maple (Acer saccharinum), wild cherries and plums (Prunus), apples (Malus), alder and birch (Betulaceae), dogwoods (Cornus), and willows (Salix). Adult food: Adults do not feed .

Reproduction

Females lay rows of 2-6 eggs on both sides of the leaves of small host trees or shrubs . Eggs hatch in 10-14 days. Young caterpillars feed in groups on leaves; older caterpillars are solitary. The cocoon is attached along its full length to a twig ; to escape predation by rodents and birds, the cocoon is usually constructed in a dark, protected area .

Behavior

Flight: One flight from March-July in most of the range ; two flights in the Midwest, from May-early June and then 2 weeks later.
