Davey, P., 2009: A local but widely spread species across Britain, the larva feeding on mosses (Musci spp.) including Tortula spp. In Dorset, this narrow-winged moth is widespread but at low density, most often recorded from the coast, and inland in areas of habitation where roofs and walls support colonies of Tortula ruralis. Larvae have also been found by Dr P Sterling on the mosses Eurhynchium praelongum and Ceratodon purpureus on Studland Dunes. A bivoltine cycle is suggested by the data, with a small proportion of the autumn brood overwintering and re-appearing during the spring.
