Depressaria cinereocostella

The combination of small size (15–22 mm wingspan), cinereous forewings with dull brownish-red overlay excluding the costa, blackish-fuscous basal suffusion, and the distinctive series of longitudinal black dashes in the fold and along veins distinguishes this species from similar Depressaria. The blackish-fuscous costal base and anal angle, plus the spotted termen, provide additional diagnostic features. Similar species in the genus Depressaria may share general pattern elements but differ in specific color distribution and spot arrangement.

Adults have a wingspan of 15–22 mm. Forewings are cinereous (ash-gray), overlaid with dull brownish red except at the costa, suffused with blackish fuscous in the basal half, and sprinkled with black and cinereous scales. A series of longitudinal black dashes runs in the fold and along the veins. The base of the costa and anal angle are blackish fuscous. A series of ill-defined blackish-fuscous spots extends from the middle of the costa around the termen to the inner margin. Hindwings are greyish fuscous, lighter basally.

Recorded from Manitoba, Nova Scotia south to Georgia, and Nebraska. Distribution records suggest occurrence across eastern and central North America.
