Davey, P., 2009: Widespread in Britain, the larva feeding on birch (Betula spp.), apple (Malus domestica), wild plum (Prunus domestica) and wild cherry (Prunus avium). The female has rudimentary wings. In Dorset, the moth appears to be rare, although moth-trapping effort is limited at such late dates. The moth has been found amongst birch at Trigon, at Norden and on The Triangle at Arne and amongst deciduous woodland in the north of the county, historically at Iwerne Minster, and more recently in Farnham Woods and in Chase Woods. It is likely to be more widespread than records indicate, and trapping in mid-November within woodland where mature birch trees grow will probably yield additional records.
