Davey, P., 2009: A local species in Britain, the larva feeding on ash (Fraxinus spp.), birch (Betula spp.), oak (Quercus spp.) and a variety of other deciduous tree species. In Dorset, this early-summer moth forms relatively small colonies very locally in the north and north-west of the county. It is chiefly restricted to deciduous woodland on the ill-drained clay soils across the Blackmore Vale and in woodland on the central and north chalk downs. Records from Melbury Park and Chedington Wood hint at colonisation of woodland on neutral clay soils further west.
Although the moth is single-brooded in the UK, second-brood examples have been recorded at Hurn, two on 19 July 1998 (M Jeffes), and on Portland, 24 July 2008 (M Cade). Continental sources are probable for these individuals, specifically western France and eastern France, respectively.
