Davey, P., 2009: A species occurring mainly along the coasts of southern England, and inland in Hampshire, Berkshire and Surrey, the larva feeding on dewberry (Rubus caesius), raspberry (Rubus idaeus) and strawberry (Fragaria spp.). In Dorset, until recently this species was restricted to the coastal fringe among bramble (Rubus fruticosus) and dewberry where it was at low density; it was rarely observed more than five kilometres from the coastal belt. Since 2001, the species has spread across the county and now appears to have colonised calcareous grassland sites and heathland sites containing good stocks of bramble. A partial second brood has been recorded at light traps following warm summers: West Bexington, on 26 September 2003 (R Eden), Portland, on 12 October 1995 (M Cade), Weymouth, 28 September 2001 (Dr P Sterling), Coldharbour, on 9 October 2006 (B Withers), Hurn, on 28 September 1999 (M Jeffes).
