Davey, P., 2009: A locally common species found in deciduous woodland in England, the larva feeding on oak (Quercus spp.). In Dorset, the moth is common in old oak/birch woodland, and at low density among oaks in open situations, such as on heathland, in parkland, and on field boundary oaks. Deciduous oak tends to be absent from coastal localities as oak cannot tolerate salt spray, and although evergreen oak (Quercus ilex) is present in some of the sites, immigration from the continent is suspected for many of the following light trap records: West Bexington, in 1998 and 1999 (R Eden), Abbotsbury Gardens, on 25 July 1997 (D Hallett), Weymouth, on 19 July 1994 (Dr P Sterling), Portland, on 20 August 1985 (N Hall), 8 and 11 August 1998, 13, 14, 28 and 30 July 1999, 26 and 27 July 2001, 25 June 2003, 7 August 2003 (M Cade), Stair Hole, on 21 July 1994 (Dr P Sterling), Swanage, on 3 September 2002 (R Cox), Durlston, on 26 August 1979 (Dr P Sterling), seven on 13 August 1991, three on 8 August 1992, four on 11 August 1997, 24 August 1999, 16 July 2003 (P Davey), on 14 August 2001, two on 26 June 2003 (S Nash), 15 July 2003, two on 5 August and three on 7 August 2003 (J McGill).
