SeasonalityMid June through July. IdentificationA medium-sized crambid (21-25 mm wingspan) with light gray brown forewings having a longitudinal median silvery white discal stripe which ends before the subterminal line. This stripe lacks a tooth below and is cut near the terminal end by a fine dark oblique line resulting in a white patch beyond the main part of the stripe. The fore wing has a falcate apex. There is a row of four 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. North American material has been referred to the race or subspecies floridus Zell. (Forbes 1920, Handfield 1997). Similar to Crambus leachellus, C. ainsliellus, C. hamellus and C. occidentalis but all lack the fine dark line which cuts across the median stripe near its terminal end and the last two species have a tooth on the underside of the median line. No published illustrations or description of the genitalia are known.
