Davey, P., 2009: A generally distributed species in Britain apart from northern Scotland, the larva feeding on the withered, decaying or mouldy leaves of, amongst others, burnet saxifrage (Pimpinella saxifraga), hedge bedstraw (Galium mollugo) and cow parsley (Anthriscus sylvestris). In Dorset, the moth is particularly common on unimproved grassland on chalky soil inland such as on the Purbeck Ridge, and on coastal grassland, notably on Portland. It is least frequent on sandy soils. The extended three plus month flight period suggests two overlapping broods.
