Davey, P., 2009: A mostly day-flying species with a scattered distribution across Britain, the larva feeding on heather (Calluna vulgaris) and bell heather (Erica cinerea). In Dorset, the moth exclusively inhabits heathland where it is usually common. The majority of adults appear during July and August, but the following examples suggest a partial first brood: Canford Heath, by day on 4 April 2002 (P Davey), Hurn, at MV light on 10 May 2000 (M Jeffes), Sopley Common, six in flight on 13 May 1997 (P Davey), Matchams, at MV light on 1 June 1988 (G Le Pard). The following moths were trapped at light in coastal localities well away from typical heathland, and dispersal is suspected: Scar Bank, on 28 July 1947 (A Russell), West Bexington, on 4 August 2003 (R Eden), Durlston, on 7 August 2003 (J McGill) and on 31 July 2004 (D Brown).
