Common in broad-leaved woodland, areas with scattered trees and heathland throughout the British Isles. Widespread and extremely common in Hampshire and on the Isle of Wight, especially during warm dry springs. Wingspan 28-32 mm. A very common early spring visitor to light traps, where the small size and relatively small orbicular stigma easily distinguishes O. cruda
from the equally common Common Quaker O. cerasi
, and less frequent Blossom Underwing O. miniosa
. Larva feeds on Pedunculate and Sessile Oak, Downy Birch, Hazel, Sallow and Field Maple.
