Common NameLeach's Crambus SeasonalityAdults have been collected in Alberta from August to mid September. IdentificationA moderately large crambid (25-27 mm wingspan) with medium brown forewings having a wide longitudinal silvery white discal stripe which ends before the subterminal line. This stripe lacks a tooth below and is not cut by an oblique line. The forewings have a triangularly produced apex. There is a row of 5 dark spots in the subterminal line. The hind wings are smoky white. The cilia of both fore and hind wings are silvery metallic. Males are similar to females. Similar to Crambus pascuellus, but the median stripe is not cut by an oblique line. Similar to C. ainsliellus but the hindwings are smoky white, not grayish white; also the gnathos of the male is narrow throughout rather than being narrow at the base, broadening distally, thus appearing spoon shaped. Similar to C. hamellus and C. occidentalis but the median stripe lacks a tooth below.
