Common NameVariegated Brindle SeasonalityAdults are on the wing in June and July. IdentificationA medium-size (3.0-3.2 cm wingspan) moth with dark grey-black wings. The thin, black antemedian and postmedian lines and the thin black line around the extremely large reniform and doubled orbicular spots of the forewings are marked by raised jet-black scales. The black antemedian and postmedian lines are preceded and followed respectively by dull red-brown scales. The basal and subterminal areas are somewhat paler, mottled with lighter grey and pale red-brown. The spots are often filled with paler grey scales, and there is a thin black terminal line. The hindwings are grey on the basal half, with a dark discal crescent, and black on the outer half. There is a prominent tuft on the thorax. The antennae in both sexes, which are similar in appearance, are simple. The dark forewing with the three large spots marked in raised black scales is unique among Alberta moths.
