Appearance
The wingspan is 40–45 mm. There are two distinct forms. The common form has pink-white patches at the base, along the costa and at the apex. There is a coppery-brown spot at the anal angle. The hindwings are brown. Form "pennsylvanica" is darker, blackish near the wing base, and does not have the pink-white patches. Adults are on wing in spring in one generation per year.
Food
The larvae feed on "Cornus" species. The larvae are dark gray black with a white ventral area.References:
