Davey, P., 2009: A species occurring throughout England and Wales, but local further north, the larva feeding on algae, lichens and mosses. In Dorset, the moth is common in marsh, bog and fen, especially where there is thick vegetation such as reed, sedge, rush or sallow scrub. Examples encountered in dry localities are probably wanderers from core damp habitat. The national norm is for the adult flight period to be in July and August; however, mid-June to late-July is the norm in Dorset.
