SeasonalityIn Alberta adult have been collected in late July.IdentificationA medium-size moth (approximately 3 cm wingspan) strongly patterned grey and black diurnal moth. Forewings are black with light grey markings, producing a strongly patterned appearance. The basal and subterminal areas in particular are banded with pale grey, and the prominent round orbicular and the reniform spot are filled with the same pale color. The postmedian line is prominently dentate. Hindwings black with a light fringe. The strongly patterned appearance and lack of any brown color will separate it from other Alberta alpine noctuids.
