No other anglewing has pronounced tails or a dot opposite a silver comma. This marking on its brownish gray underside resembles a question mark, giving it its name. The Question Mark butterfly has a wingspan from 4.5 to 6.8 cm. Its wings above are orangey-brown with black spots and violet-edged hind wing tails.
Late May until early July you might see this butterfly in forested areas with some open fields or meadows, on roadsides and near streams in the Algonquin Highlands.
Usually with 2 broods per year, females lay light green, keg-shaped, and ribbed eggs singly or stacked under leaves of plants that are usually not food for the coming larvae. Caterpillars, reddish brown with lighter spots, must find an Elm or some nettle; they then eat leaves and live alone.
Adult prefer to feed on rotting fruit, tree sap, dung, and carrion, rarely drinking nectar.
