This subspecies is transcontinental in the Canadian and Transition zones. Its habitat is various kinds of mesophytic or damp woods. Adults occur throughout the growing season. Hibernation appears to be as adult females. Various larger or medium-sized Lepidoptera in forests serve as hosts, particularly those pupating on tree trunks.
