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. Wingspan 47-54 mm.
it has been proved empirically that the only safe way of separating this species as an adult from the closely related Copper Underwing A. pyramidea
is to view the underside of the hindwings. Please see that species for a comparative photo.
the underside of the hindwing's discal area is a pale straw yellow which contrasts with the orange-copper shading of the terminal area. In berbera
this discal area is suffused orange-copper in the dorsal half which continues to the termen.

Larva feeds on Pedunculate Oak, over-wintering as an egg.
