Davey, P., 2009: A declining species headquartered in south-east England mainly on chalk downland, the larval foodplant is unknown. In Dorset, the moth has always been rare and after a gap of seventy years, several were trapped at light during the 1960s in the north-east of the county in the lee of chalk downland. Thirteen years later, one more was trapped in similar chalky habitat but fifteen kilometres away. There have been no further records, although a colony persists at Stourhead, three kilometres to the north of the county border in Wiltshire. Given the recent serious decline of the species nationally and the loss of much of its preferred unimproved chalky grassland habitat, the moth is probably extinct in the county, no recommendations are proposed: Glanvilles Wootton, in 1881 (Dale), Bere Wood, at sugar on 23 July 1856 (FB), Iwerne Minster, at MV light on 30 June 1956, 30 June 1959, 1 July 1959, 5 July 1968 (H Moore), Milton Abbey, at MV light on 18 June 1981 (Milton Abbey School NHS). It is recommended that trapping be undertaken at Fontmell Down for this species.
