Comadia albistrigata

Distinguished from similar Cossidae by the combination of: creamy white subcostal stripe on forewing (without checks), brown checkered costa, and uniformly mouse brown hindwings. Small size and southwestern U.S. range further support identification. The pale subcostal stripe is the most diagnostic feature.

Small moth with forewings 11–14 mm in males, approximately 13 mm in females. Forewing costa has brown checkered pattern. Subcosta is creamy white without checks, creating a prominent pale stripe. Discal area of forewings is mouse brown. Hindwings are uniformly mouse brown without pattern.

Southwestern United States: Arizona, New Mexico, and Texas.

Adults active May to June.
