Davey, P., 2009: An irregular immigrant species to Britain and extinct resident, the larva feeding on aspen (Populus tremula). The species was resident in Orlestone Forest in Kent between 1935 and 1955 before the aspen trees within the wood were felled to make way for conifers. In Dorset, this spectacular moth has been recorded on nineteen occasions in the past twenty-seven years either at sugar, at light or during the day. All county records follow; most are from light traps unless stated otherwise: West Bexington, on 15 September 2005 (R Eden), Lyons Gate, by day on house wall on 25 September 2005 (T Box), Radipole, worn female at rest by day on 2 October 1954 (L Summer Ward), Puddletown, at MV on 20 September 1999, 12 September 2006, 7 and 20 September 2007 (H Wood Homer), Shaggs, on 29 September 2005, 20 September 2006 (Butterfly Conservation), to house-lit first-floor window whence netted on 7 September 2008 (L Hill), East Holme, 1 October 2007 (J Cox), Spetisbury, 7 September and 7 October 2008 (D and Mrs J Kingland), Langton Matravers, on 9 August 1986 (E Groves),on 30 September 1994 (D Kemp), Studland, on 23 September 2006 (C Manley), Poole, in 1866 (E Blanchard), Longfleet, at rest on ash tree in 1892 (W Parkinson Curtis), Swanage, at sugar on 20 September 1938 (C Cole), at sugar on 29 August 1939 (P Whitehouse), Branksome, in 1945 (W Parkinson Curtis), Parkstone, at lighted window on 11 September 1976 (Miss Brotherton), Verwood, at house light on 7 September 2008 (C Hill), Boveridge, about 1740 (Storey), Matchams, on 13 September 1985 (G Le Pard), Iford, on 11 October 1995 (M Jeffes), Highcliffe, at rest on house wall on 10 September 1982 (E Wild).
Occurrences of this species have evidently increased of late, and residency is just possible for recurring examples trapped in the Piddle and Frome river valleys. Although the majority of record dates coincide with airflows from the Continent, the 7 September 2007 example at Puddletown occurred following a ten-day period of north to north-westerly winds.
Hill, L., 2013: For the period 2010 to 2013 there’s been a further 42 records from 20 sites.
