Davey, P., 2009: A common species in Britain, the larva feeding on birch (Betula spp.), sallow (Salix spp.), oak (Quercus spp.), alder (Alnus spp.) and other deciduous trees and shrubs. In Dorset, the moth is frequent in deciduous woodland and scrub. Singletons appear elsewhere from time to time. The national norm is of a double brood in southern England and a single brood in northern Britain. The relatively high numbers between the respective double brood peaks in early-June and mid-August suggest an additional univoltine cycle in July. The very few moths seen in October are likely to represent a partial second brood spawned by the univoltine brood.
