Species Account

Sutton & Beaumont, 1989: Not recorded since Porritt (1983-86, 1904) and only then from Sheffield (VC63), York and Scarborough (VC62). At the last site it would appear that there was a small colony between 1898 and 1900 (Hewett, 1901). This species still occasionally turns up in Lincolnshire (Duddington & Johnson, 1983) and is still resident in Sherwood Forest, Nottinghamshire (Bcc, 1988) so it is not far short of Yorkshire in range.

Current status (CHF, 2011): Last recorded 1900. Doing well in its main haunts in the south of the country, as far north as oak woodland in Lincolnshire. There are no signs of a range expansion but it would not need much of a northwards push to reach Yorkshire.
