The Colorful Zale Moth is on the wing in spring and early summer in mixed hardwood-conifer forest at lower elevations. They are nocturnal and attracted to lights, so you may see them resting during the day with their wings spread flat out to the sides. They, along with other members of this genus (Zale), often have continuous color patterns extending across both the forewings and hindwings. Larvae are generalists and feed on a variety of hardwood trees and shrubs in the birch, rose, heather, maple and willow families. This species is widespread in North America.
