Davey, P., 2009: A widespread species in Britain found in marsh, fen and bog habitat, the larva has been reared from moss (Musci spp.) and may also feed on lichens (Usnea spp.). In Dorset, the moth was very local and resident populations were historically, restricted to the wettest habitats in the Poole Basin. However, many recent records have been from other habitats, particularly unimproved dry grassland sites on chalky soil. Abroad the species is stated to frequent meadows and woodland edges where the larva feeds on mosses, and it is possible that the warming trend has caused influxes of a strain of this species that inhabits drier biotypes on the Continent that has managed to become resident this side of the Channel.
The national norm is for a single-brooded species in June and July, but in Dorset, the moth is evidently bivoltine, again possibly a reflection of the Continental strain. The weak markings, pale grey/brown ground colour and relatively narrow forewings combine to make this a relatively distinctive species.
