Davey, P., 2009: A common species in Britain, the larva feeding on lady's bedstraw (Galium verum), goosegrass (Galium aparine), knotgrass (Polygonum aviculare) and other herbaceous low-growing plants. In Dorset, the moth is common to abundant on chalky soils. It is recorded in marsh and river habitat where it is possibly associated with common marsh-bedstraw (Galium palustre) and fen bedstraw (Galium uliginosum); also on clay soils and in nutrient-rich arable land where goosegrass and knotgrass abound, respectively. It is least frequent on open heathland.
