Euxoa atristrigata
Smith, 1890
Euxoa atristrigata is a noctuid described by Smith in 1890. It occurs in western North America from British Columbia and Saskatchewan southward to California. As a member of the Euxoa, its larvae likely share the habit of feeding at or below the soil surface on plant stems, though species-specific remains poorly documented.

Identification
Euxoa atristrigata can be distinguished from similar Euxoa by examining genitalic characters and forewing pattern details. The specific epithet "atristrigata" (meaning "black-striped") suggests dark longitudinal markings on the forewings, though precise diagnostic features require reference to original description or revisionary works. Separation from Euxoa messoria and other western Euxoa species typically requires dissection and comparison of male genitalia structure.
