Davey, P., 2009: A central and southern European species, resident in the south-east coastal regions of Jersey and Guernsey, and a scarce immigrant to the coasts of south and south-east England, the larva leading a subterranean existence feeding on the roots of grasses and plants, and recorded as a serious pest in vineyards. In Dorset, singletons have been seen on twenty-three occasions, all but four from Portland and all at light traps. Many of the dates coincided with immigration from abroad, but a transient colony may have become established for several years following the hot summer of 2003 on Portland: West Bexington, on 9 August 2004 (R Eden), Wyke Regis, on 7 August 2003, 13 August 2004 (D Foot), Portland, on 19 August 1987, on 6 August 1989 (F Clafton), on 2 August 1991, 30 July 1992, 5 August 1994, 27 July 1995, 7 August 1995, 5 August 1996, 11 August 1997, 12 and 17 August 2004, 1, 6, 14 and 16 August 2005, 24 August 2007, 16 August 2008 (M Cade), on 4 August 1994 (B Skinner), Southwell, on 8 August 2005 (via PBO), Swanage, on 30 July 2008 (R Cox).
