Description


The wingspan is 46–50 mm.The forewing ground colour is usually grey-brown. The same coloured midfield is bordered by blackish crossbars that are often partly white. At the wing edge below the apex are two characteristic, protruding teeth. The scientific name of the species is derived from the Latin language bi = "twice" and dentatus= "toothed".The outer dark cross line of the forewings continues on the hindwings. All wings have a ring-shaped dark discal spots. The thorax is hairy. This is a very variable species with the wing colour ranging from whitish through buff and brown to black, sometimes with variegation, but it is always easily identifiable by the white discal spot on each wing and the characteristic "ragged" margin of the wings.


The adults fly at night in May and June[1] and are attracted to light.
