Davey, P., 2009: Resident and rare on coastal sand dunes and shingle beaches in Kent, Suffolk and formerly Essex, otherwise a very rare immigrant, the polyphagous larva feeding on withered leaves of herbaceous plants and grasses. The moth has a mainly southern distribution in Europe where it colonises open dry grassland. In Dorset, three individuals have been recorded on or close to the coast and all are suspected immigrants: Portland, at MV light on 15 July 1994 (M Cade), near Bournemouth, 19 July 1900 (Robertson, 1900, Entomological Record, 12:300, 341), Branksome (All Saint's Fields near Branksome Parish Church) on 18 July 1901 (E Todd).
