SeasonalityAdults have been collected in Alberta in August.
IdentificationA medium-size (3.8-4.0 cm wingspan) contrasting grey and black moth. Forewings are smooth, almost iridescent pale violet grey and dark slate grey. The basal area and the areas distal to the postmedian and subterminal lines are pale violet grey, while the median area, especially around and below the stigma, and the area along the basal side of the subterminal line is dark slate grey and black. The stigma is a small, silvery white v-shape with an extension to the antemedian line. Forewing pattern is very attractive, and unlike any other Alberta moth. Hindwings are dark sooty grey-brown, antennae are simple, and both the sexes are alike.
