Davey, P., 2009: A species occurring most frequently in south-eastern Britain, but rare in northern Britain, the larva feeding on the inner stems of various grasses including tall fescue (Festuca arundinacea), tufted hair-grass (Deschampsia cespitosa) and false oat-grass (Arrhenatherum elatius). In Dorset, the moth occurs in a variety of different habitats. It is common on unimproved grassland on clay soils and chalk downland, and locally abundant on coastal undercliff; in these situations, tall fescue and false oat-grass are probable foodplants. It is at low density in dune habitat at Studland, Brownsea Island and Hengistbury Head where lyme-grass (Leymus arenarius) or sand couch (Elytrigia juncea) may host the moth. It is also at low density in river, fen, marsh, lagoon and harbour habitat suggesting reed-canary grass (Phalaris arundinacea) as the host plant in these damper places. The national norm of a single brood between late-July and early September holds true for Dorset, but a partial first brood in June is also indicated by the records.
