Identification

are medium-sized noctuid with a wingspan near 34 mm. Distinguishing Feltia subgothica from other dart moths (Feltia and related ) requires examination of genitalic structures and subtle wing pattern differences not reliably visible in field conditions. The species is part of a complex of similar-looking cutworm moths that are often difficult to separate without dissection.
