Davey, P., 2009: A species widely distributed across southern England but local elsewhere, the larva feeding on oak (Quercus spp.). In Dorset, the moth is confined to oak woodland where it is common; elsewhere it is rare or absent. A very late (or very early) example follows: Garston Wood, at MV light on 8 November 1983 (Miss E Samuel).
