Identification TipsHighly variable in coloration and markings, making identification challenging. Look for the overall drab brown/gray appearance, typical dart moth forewing patterns (orbicular, reniform, claviform spots, though often obscure), and generally pale hindwings. Examination of genitalia may be required for definitive identification from similar *Agrotis* species.
Description
