Davey, P., 2009: A widespread species in Britain, the larva feeding on birch (Betula spp.), sallow (Salix spp.), alder (Alnus spp.) and honeysuckle (Lonicera spp.). In Dorset, the moth is common amongst the birch/heather terrain on sandy soil, mature birch growing in woodland on chalky soil in north-east Dorset, and in the valley swamps of Powerstock Common where alder is dominant. The moth is seldom encountered well away from these core heathland and wetland habitat types.
