Davey, P., 2009: A local species found mainly in southern England, the larval foodplant is unknown. In Dorset, the moth is restricted to chalky soils where it is at low density, rising to frequent only very locally. Abroad, the foodplants include common rock-rose (Helianthemum nummularium), plus wormwoods and mugworts (Artemesia spp.).
Many of the unimproved grassland localities where the moth is found in Dorset support common rock-rose: Portland, (C Partridge), not uncommon near the rifle range (N Richardson), The Verne, three at MV light on 19 June 1998 (Dr J Clarke), Puddletown, at MV light on 28 June 2000 (H Wood Homer), Winfrith, in 1997 (J Hunnisett), Lulworth Cove, by day on 23 June 1995 (R Heckford), Arish Mell, four at MV light on 31 May 2003, and Melbury Down, at MV light on 11 July 1994 (P Davey), three on 18 July 1994 (R Cook), Hod Hill, (C Dale), West Hill, at MV light on 23 June 1998, 14 July 1998 (P Davey), Badbury Rings, (W Parkinson Curtis), on 16 July 1996, fourteen on 9 June 1997, and St Albans Head, at MV light on 31 May 1992, 23 June 1994 (P Davey), Seacombe, (Reverend E Bankes), at MV light on 3 July 2001 (C Manley et al), Woolgarston, at MV light on 1 July 1994 (R Burt), Knowle Hill, and Ballard Down, and Swanage, (C Dale), Bottlebush Down, (W Parkinson Curtis), at MV light on 11 June 1997, two at dusk on 28 June 1997, 7 July 1997 (P Davey), Handley Down, (W Parkinson Curtis).
