Davey, P., 2009: A local species in Britain found in northern England and northern Scotland, the larva feeding on birch (Betula spp.). The moth is resident in southern Scandinavia, Denmark and Holland. In occurs also in eastern Belgium and in eastern France where it is chiefly an upland or montaine species. In Dorset, the moth has been recorded on six occasions: West Bexington, 24 August 2007 (R Eden), Iwerne Minster, on 30 August 1968 (H Moore), Portland, on 30 July 1991 (M Cade), Stoborough, on 28 July 1984 (B Withers), Slepe Heath, on 18 July 1982 (D Brown), Arne Wood, on 18 July 1982, 18 September 1982 (B Pickess). All are likely to have been immigrants from abroad: Scandinavia for the 1968, 1982 and 2007 examples, and central or northern Europe for the 1984 and 1991 moths.
