Davey, P., 2009: A resident species in woodland on chalky soil in Sussex and Kent between 1847 and 1880 and noted as a rare immigrant subsequently, the larva feeding on deciduous trees at first and later on herbaceous plants. It is locally common within deciduous woodland throughout much of Europe, but absent from southern Iberia. Seventeen moths have been recorded in Dorset; all are suspected immigrants and nearly half of the tally appeared during the autumn of 2004 when a source of central France was likely. Several examples were then seen the following spring and are likely to have hibernated post-immigration. The two West Bexington moths from 2004, a male and a female, were retained and kept in a fridge over the winter. The two were then brought together, paired, and the female duly laid in the region of six hundred ova. The larvae were successfully reared on birch (Betula spp.) and elm (Ulmus spp.). West Bexington, at MV on 5 November and on 11 November 2004, 28 October 2006 (R Eden), Portland, at MV on 27 November 1997, 3 November 1999, two on 2 November, one on 6 November and one on 7 November 2004 (M Cade), Weymouth, at MV on 31 March 2005 (R Lambert), Puddletown, on 28 October 2005 (H Wood Homer), Durlston, on 2 November 2004 (S Nash), two on 27 October 2005 (D Brown, M Townsend), 28 October 2006 (A Jenkins), Canford Cliffs, at MV in March 2005 (Mrs P Taylor), Bournemouth, on 14 October 1902 (Major R Robertson), 7 November 1902 (W Hooker).
