About Agrotis bigramma (Esper)
Agrotis bigramma, commonly known as the great dart, is a moth species belonging to the family Noctuidae. The species was first described by Eugenius Johann Christoph Esper in 1790. Its established distribution ranges from the southern shore of the Baltic Sea to China, the Levant, and North Africa. Migrant individuals of this species have been recorded as far west as Great Britain; three migrants were caught in a single trap at St Agnes, Isles of Scilly on 10 August 1997. This moth has a wingspan measuring 40 to 48 millimeters. Adults are active from September to December each year. Agrotis bigramma produces one new generation per year. The larvae of this species feed on the roots of grass species in the Poaceae family, as well as the roots of other low-growing herbaceous plants.
