Davey, P., 2009: A local species in Britain, the larva feeding on oak (Quercus spp.), birch (Betula spp.) and rowan (Sorbus aucuparia). In Dorset, the moth is common in deciduous woodland containing mature birch and oak. It is also frequent on the coast where evergreen oak (Quercus ilex) is the likely host foodplant, for example at Durlston, Branksome Chine and Highcliffe. Male moths perish before year-end, but females hibernate and then slowly re-appear, mainly during the late spring. The absence of males helps explain the much smaller post-winter population.
