Common NameDimorphic Bomolocha, Toothed Snout-Moth SeasonalityAdults have been collected in Alberta from late May through early July. IdentificationA medium-size (2.4-3.1 cm wingspan) broad-winged moth with pointed wings; The males and females are very different in appearance. The male is dull black, with the lines obsolete except for a few paler dots on the veins. The only prominent marking is a small white patch on the lower edge of the forewings. The female, which is a bit smaller than the male, has the basal half of the forewings black, outlined with a thin white line except for a narrow light brown patch along the bottom. The outer half of the forewings are pale brown, almost white where they meet the black basal half, and darkening towards the outer margin. The subterminal line is marked by a series of large, blurred grey spots, and there is a short dark streak from the subterminal line to the apex. The hindwings are dark grey-brown, unmarked. The antennae in both sexes simple.

Diet Info No Alberta data; elsewhere in Canada the reported hosts are Alternate-leaf, Western Flowering, and Red-osier dogwoods. (Cornus sp.). Range From Nova Scotia (the Type Locality) across southern Canada to Vancouver Island, south to Florida. In Alberta, it has only been collected in the Edmonton area.
