Davey, P., 2009: A local species in Britain, the larva feeding on alder (Alnus spp.). In Dorset, the moth is common in the valley swamps at Powerstock Common and in St Leonard's Peats within Hurn Forest where alder is the dominant tree species. The moth is also frequent in river courses and streams where alder occurs. It is seldom encountered far from damp alder-rich habitat.
