Davey, P., 2009: A widespread woodland species in Britain, the larva feeding on beech (Fagus sylvatica), hazel (>Corylus avellana) and birch (Betulae spp.), and other deciduous trees. In Dorset, the moth is widespread and ranges from frequent to common in beech plantation and woodland containing substantial hazel understorey, to occasional in open habitat. The peak of the second brood is roughly one third smaller than that of the first brood. Potential third brood examples recorded in warmer than average summers follow: Iwerne Minster, at MV on 9 October 1955, 25 September 1967 (H Moore), Shaggs, at MV on 27 September 2001 (M Parsons).
