Davey, P., 2009: A generally distributed species in Britain, the larva feeding on lady's bedstraw (Galium verum), hedge bedstraw (Galium mollugo) and heath bedstraw (Galium saxatile). In Dorset, the moth occurs at low density in scattered colonies across three rather different habitat types. The first of these, and where the moth is most frequently encountered, is unimproved dry chalk grassland where lady's bedstraw and hedge bedstraw are frequent, both on the coast and inland. The second habitat is wet woodland containing fen bedstraw (Galium uliginosum) on alluvial soils and clays in north-west of Dorset, for example, Powerstock, Bracketts Coppice, plus several localities in the Poole Basin, notably Withy Wood at Hengistbury Head. The third habitat is river and water meadow, where fen bedstraw and common marsh bedstraw (Galium palustre) occur; Milton-on-Stour and Woolland and localities for the moth.
