Species Account

Sutton & Beaumont, 1989: This species was described as 'very rare' by Porritt (1883-86), only having been recorded from Sheffield (VC63) and Askham Bog (VC64). It was not recorded again in the County until 1971, when single specimens were captured at Spurn (VC61) on 17 and 21 July by B.R. Spence. This species has a curious distribution in Britain, being concentrated in the South but having a northern colony in Northumberland. The Spurn specimens probably originated from the South since there have also been recent records in Lincolnshire.

2012 (CHF): This species has undergone a massive national decline and has disappeared from nearly all of its previous areas. There are few recent records anywhere in the country so we are not likely to see it again in the county.
