Davey, P., 2009: A species occurring throughout Britain, the larva feeding on alder (Alnus glutinosa), oak (Quercus spp.), birch (Betulae spp.) and hazel (Corylus avellana). In Dorset, the moth is primarily a denizen of old oak/birch woodland and birch on heathland, and in these habitats it is frequent. It is infrequent elsewhere and becomes rather rare in open tree-less habitat. The national norm is a single brood in northern Britain in June and July, and a double brood in the south. In Dorset, the flight period covers four months. This is suspected of comprising a single brood with a peak in early July, plus a double brood with peaks in mid-May and early August. In this latter cycle, the peak of the second brood is on average, two times larger than the peak of the first brood.
