Species Account

Sutton & Beaumont, 1989: This is a rare immigrant to the British Isles and usually only reaches the South of the country. The unusually hot summer of 1976 resulted in over twenty specimens being recorded in Britain (Skinner, 1984), two of which were in Yorkshire. These were the first since Porritt (1883-86,1904) when five specimens had been found from 1858 to 1896.

Argus 54, 2007: Amazingly, in a poor migrant year, this spectacular moth turned up south of Ripon!
VC64. Bishop Monkton, 8.9.2007 (D&DB). NEW VICE-COUNTY RECORD.

2012 (CHF): There seem to have been six records since Porritt, so 11 in total. None seen since 2007.
