Species Account

Sutton & Beaumont, 1989: In 1976 the first record of this species occurred since Porritt's list (1883-86) and it has now been recorded in all five vice-counties.

2012 (CHF): Widespread across the county but in smaller numbers than Brindled Pug with which it is often confused. Oak-tree Pug is smaller and paler with a smaller broader discal spot and a pale patch distal to this. The peak flight time is 2-3 weeks later than Brindled Pug.
