Davey, P., 2009: A widespread species in Britain, the larva feeding on broom (Cytisus scoparius). Broom is a local and decreased plant species confined to sandy soil in Dorset where it forms small, scattered communities on heathland, and otherwise is grown as an ornamental shrub in gardens in towns. The moth is very local, at low density, and recorded almost exclusively where broom is most frequent. Repeat records have been noted from Furzebrook, Ashington, Merley, Canford Heath, Parley Common, St Ives and Matchams.

Occasionally, moths appear in atypical localities where broom is not found, particularly on or close to the coastal belt between Portland and Purbeck. A continental source is suspected for the following light trap records given the onshore airflows at the time: Portland, 27 October 2001 (M Cade), Shaggs, 10 November 2003 (BC), Durlston, five between 27 and 28 October (Dr J Clarke, P Davey), Scar Bank, 16 and 22 October 1938, 23 October 1953 (A Russell).
