SeasonalityThe Alberta specimen was collected June 27, 2007. IdentificationA relatively small (2.3-2.6 cm wingspan) moth with white wings with dark basal and terminal areas. The forewings are white with very dark red-brown basal area and a red-brown terminal area suffused with white scales. The median area has a broad brown band overlain with white scales creating a “ghost-like” appearance in some specimens. The orbicular is indicated by a small black dot and the reniform by a small black crescent. Hindwings white with the basal half light blackish brown, a broad terminal band of the same color followed by a white fringe and a prominent dark discal mark. Antennae simple and sexes similar. It bears a superficial resemblance to some of the small flower moths (Heliothinae).

Life History Almost nothing is known. Adults are nocturnal and come to light. Diet Info Nothing is known of the early stages and larval hostplants.
