Dark Crimson Underwing
The grey forewings are crossed by jagged cross-lines and bands. The red hindwing which gives it the English name has a black band around the scalloped margin, fringed with white. Another irregular black band runs across the centre of the red patch of the hindwing.
The larvae can be found from May to July feeding at night and hiding under loose bark or in a crevice during the day. They overwinter as eggs.
Black-poplar (Populus nigra), White Poplar (Populus alba), Aspen (Populus tremula), other poplars and willows.
Woodland, parkland, scrub, riverbanks and gardens.
