Davey, P., 2009: A species restricted to southern England, the larva feeding on oak (Quercus spp.). In Dorset, the moth is common in oak woods, but scarce otherwise. The national norm is for adults to be on the wing in late July and August; it is likely that the following are second brood individuals: Arne Wood, on 10 October 1985 (B Pickess), Hurn, on 24 September 1998 (M Jeffes). Dispersal from outside the county or immigration from abroad may account for the following light trap records during 2004: Walditch, on 7 August (M Parsons), West Bexington, on 25 July (R Eden), Preston, on 27 July, 28 July (R Lambert).
