Notes: Common in woodland, scrub, hedgerows, gardens and parks, throughout much of England, Wales and southern Scotland; in Hampshire and on the Isle of Wight, distribution poorly known due to confusion with A. pyramidea, but there is, as yet, no conclusive evidence that either species is present in an area where the other is not [MoGBI]. Wingspan 47-54mm. For a method of separating this species from the closely related Copper Underwing A. pyramidea using palp characteristics, click here. Larva feeds on Pedunculate Oak, over-wintering as an egg.
