SeasonalityLate July and August. IdentificationA medium sized Crambus (24-27 mm wingspan). Forewing yellowish gray with a thin stripe along the anal margin and one below the costa; discal stripe narrow, not widening towards the apex, with a slight tooth below at the inner third; lacking a white patch between the discal stripe and the subterminal line; terminal line with four or five black dots below. Regarded as a synonym of C. dumetellus by Fernald (1896) but shown not to be so by Kearfott (1908). Crambus dumetellus is now regarded as a synonym of C. whitmerellus. Crambus trichusalis is easily separated from whitmerellus by having the narrow discal stripe which does not widen towards the end.
