Davey, P., 2009: A local and declining species in southern Britain, the larva feeding on elm (Ulmus spp.). In Dorset, the last resident moth was seen more than thirty years ago at the time when all mature elms across the county were beginning to succumb to the Dutch elm disease. It may still hang on at very low density in one or two localities, for example Warre Wood, see below, however its decline nationally suggests otherwise. All county records follow: Charmouth, (WDL), Sherborne, (Dale), Glanvilles Wootton, (Dale), Upwey, at MV on 19 July 64 (Brigadier H Warry), Warre Wood, at MV on 23 August 2003, female on 14 August 2004 (D Foot, Dr P Sterling), Portland, (C Partridge), Iwerne Minster, at MV on 25 August 1954, two on 10 August 1956, 5 September 1959, 29 July 1960, 24 July 1964, 4 August 1966, 10 August 1966, 21 August 1966, 28 July 1967, 24 August 1968, 26 August 1968, 30 August 1968 (H Moore), Chamberlaynes, at light on 10 August 1929, at sugar bait on 14 July 1935 (H Andrewes), Bloxworth, a few bred (O Pickard Cambridge), (W Parkinson Curtis), Spettisbury, (S Scarsdale Brown), Furzebrook, at MV on 16 August 1973 (Professor N Webb), Badbury Rings, (W Parkinson Curtis), Corfe Castle, (Reverend E Bankes), Pamphill, (W Parkinson Curtis), Hamworthy, (W Parkinson Curtis, E Curtis), Poole, (W Parkinson Curtis), Canford, at MV on 18 July 1953 (A Kennard), Studland, (Reverend C Digby), Scar Bank, at light on 29 July 1934, 8 August 1934, 1 August 1935, three on 25 July 1952 (A Russell), Sandbanks, (W Parkinson Curtis), Cranborne, plentiful (F Fisher), Kinson, (S Scarsdale Brown), Bournemouth, fairly common (Fassnidge).
The following examples were trapped more recently amidst immigrant activity: Upwey, 19 August 2002 (P Harris), Portland, on 2 August 1995, 3 August 2003 (M Cade), Preston, on 9 August 2003 (M Forster), Durlston, on 7 August 2003 (J McGill), Hurn, on 2 August 2001 (M Jeffes); northern France is a potential source on each occasion.
