Davey, P., 2009: A rare species occurring locally in most southern coastal counties prior to the middle of the last century but from the 1970s, restricted to Devon, Hampshire and Kent, the larva feeding on oak (Quercus spp.). In Dorset, this beautiful moth was recorded nearly one hundred years ago in the far north-east of the county. Although much of the old woodland in the area was sacrificed to coniferisation from the 1960s, two old oak woods remain to the present day, and fortunately still support the species. A continuation of the sympathetic management employed at Boys Wood and at Castle Hill Wood could be beneficial to maintaining this species at both sites: Cranborne, on 10 June and 19 June 1905 (F Fisher), larva (W Parkinson Curtis), Boys Wood, at MV light on 13 June 2002 (P Davey), Castle Hill Wood, at MV light on 18 June 2003 (P Davey).

One further moth was seen during 2003 flying in warm sunshine before landing on a gorse bush close to the observer: West Moors, on 29 May 2003 (K Powrie). Since 2003, the species seems to have undergone a rapid expansion in the north-east of the county, the following light trap records refer: Verwood, on 3 June, 16 June and 29 June 2007 (M Weaver), 8 June 2008 (C Court), at house light on 2 July 2008 (C Hill), Alderholt, at MV light on 31 May, 9 June, 24 July 2008 (T Morris). The following example was trapped well away from core habitat, and coincided with immigration from abroad: Dorchester, at MV light on 21 June 2003 (J Down).
