Common in woodland throughout much of the British Isles, but not in northern Scotland. In Hampshire and on the Isle of Wight widespread and common. Wingspan 11-15 mm. The nominate form, in which the forewing markings contrast with the ground colour, is reminiscent of
G. sociana but can be distinguished by the cream-white frons and vertex of the head, which in
G. sociana are clear white; the coloration of the head also distinguishes
G. dealbana from other British
Gypsonoma species [Bradley]. Larva feeds within buds and young shoots of Hazel, Hawthorn, Poplar and Sallow, subsequently living within a leaf-fold.
