Species Account

Sutton & Beaumont, 1989: There are now six known sites in Yorkshire for this species and there may well be more as it is very easy to overlook (AMR pers. comm.).

2012 (CHF): Records have increased since 1989 with most coming from the magnesian limestone belt which runs down the centre of the county and there have now been records further north in Durham. One of the smallest Pugs and flying the same time as Slender Pug with which it is easily confused. Unless you are really confident you can separate these two species, it should be dissected.
