Habitats and Life History
Habitats: Schmidt and Anweiler (2020) describe this species as associated with cool, temperate, moist-to-wet woodland habitats. Our records come from alluvial and cove forests at low elevations in the Mountains and more commonly in high elevation forests.
Larval Host Plants: Larvae feed on a wide range of hardwood trees and shrubs, including Alder, Apple, Beech, Birch, Cherry, Mountain Ash, Plum, Rose, Serviceberry, and Willow (Wagner et al., 2011). Species in the Rosaceae seem to be preferred, with members of the Betulaceae also commonly use (Schmidt and Anweiler, 2020).
