Davey, P., 2009: A local species in Britain, the larva feeding nocturnally on birch (Betula spp.) and on sallow (Salix spp.). In Dorset, the moth is restricted to birch-rich localities particularly in deciduous woodland where the moth is frequent, but also in more open habitat on heathland. The moth has no preference for soil type; the presence of birch seems to be the over-riding factor. The national norm is a single brood in late-July and August, but in Dorset the moth appears in early July and is all but gone by the middle of August. The following individuals were trapped late in the year coinciding with high immigrant activity: Arne, two on 11 October and two on 12 October 1995 (B Pickess).
