Davey, P., 2009: A species confined to and frequent along the coasts of England and Wales, but local along the eastern seaboard, the larva is polyphagous on herbaceous plants. In Dorset, the moth is abundant in undercliff habitat on Purbeck and on Portland. A total of nearly one thousand moths was trapped in Swanage town by Rees Cox in the 1997 season alone. Elsewhere, the moth is at low density on sandy coasts including Poole Harbour and Christchurch Harbour, but becomes increasingly scarce the further west one travels from Portland. It has also colonised chalky soil in the Dorchester area and along the Purbeck Ridge, and in this latter locality is locally frequent. The following dispersed examples were observed at light traps well inland some distance from known colonies: Chamberlaynes, on 17 October 1938 (H Andrewes), Powerstock, on 4 October 1997 (D Foot, M Forster), Trigon, on 27 September 1997, 17 October 1997, 22 and 28 September 1998 (CM), Shapwick, on 29 September 2003 (P Davey), Gaunts Common, on 11 October 1993, 16 September 1996 (P Davey), Ferndown, on 9 October 2003 (R Cook), St Ives, on 5 October 1987 (Dr J Clarke). A number of individuals trapped in mid-summer in recent years suggest a partial first brood.
