Davey, P., 2009: A rare and declining species in southern Britain, the larva feeding on the sucker shoots growing out of the trunks of mature elm (Ulmus spp.). In Dorset, the last moth was seen nearly thirty years ago at a time when mature elms across the county were beginning to die from Dutch elm disease. It is very doubtful that the species is still resident in the county. In the absence of any initiative to restock the countryside with disease resistant elm, no recommendations are proposed: Charmouth, (Dale), Glanvilles Wootton, (Dale), Sutton Poyntz (R Stewart), Dorchester, at MV light on 7 September 1962 (Dr J Hasler), Kington Magna, at MV light on 2 September 1954 (H Moore), Winfrith, (Dr F Haines), Cranborne, (F Fisher), Furzebrook, at MV light on 3 and 16 August 1975, 9 and 14 August 1976 (Professor N Webb), Bournemouth, fairly common (Fassnidge).
