Davey, P., 2009: A local species restricted to southern and western districts of England, the larva feeding in spun leaves of oak (Quercus spp.). In Dorset, thirty-one examples have been recorded on seventeen occasions, many of these from light traps and most fall within the last ten years following an absence of ninety years. All of these are suspected immigrants from the Continent; dates coincided with notable influxes of other migrant Lepidoptera. The wind rose indicates the direction of the airflows on the associated dates, and the strong bias towards a south-easterly quarter suggests a central or southern European source for many of the individuals: West Bexington, on 31 August 1998 (R Eden), 1 September 1998 (Dr P Sterling), Glanvilles Wootton, on 4 July 1870 (J Dale), 15 July 1901 (C Dale), Wyke Regis, on 4 July 2006 (D Foot), Portland, two on 1 September 1998, two on 4 and one on 8 July 2001, 23 and 26 June 2003, 14 July 2003, 27 June, two on 3 July, 9 July, 13 July 2005, on 6 and 19 July 2006 (M Cade), Weymouth, on 24 August 1999 (Dr P Sterling), Preston, on 25 and 26 June 2003 (R Lambert), Gaunts Common, on 3 August 1994 (P Davey), Durlston, four on 31 August 1998 (P Davey), 4 July 2001, 3 September 2002, 25 June 2004, 21 July 2006 (S Nash), three on 26 June 2003 (P Davey), on 14 August 2004 (C Manley), Studland, on 7 August 1904 (Reverend F Fisher), Iford, on 4 August 1994 (M Jeffes).
