SeasonalityAlberta specimens have been collected from June 20 to September 17.IdentificationA small (11-17 mm wingspan) Tortricid moth of the subfamily Olethreutinae. The forewings are light brown, narrow-pointed at the apex and with a number of darker brown areas. The hind wings are sooty-brown in color. Similar in appearance to Bactra furfurana but easily distinguished by the male genitalia as the cucullus bears stout spines. Illustrations of the latter are in both Heinrich (1926) and Miller (1987).
