Davey, P., 2009: A common species in Britain, the larva feeding on birch (Betula spp.), beech (Fagus spp.), oak (Quercus spp.), elm (Ulmus spp.), hawthorn (Crateagus spp.) and various other deciduous trees. In Dorset, the moth is common in deciduous woodland and frequent in deciduous scrub and thickets. It is rare in conifer plantation, in open grassland and on heathland. "Larvae may eat lichens (Usnea spp.) and mosses on oak, on alder (Alnus) and on beech tree trunks" (W Parkinson Curtis ms). The national norm is a single brood between July and early August, with a partial second brood in southern England between late August and the end of September. However, the moth is bivoltine in Dorset with the first brood on the wing from the end of May.
