Species Account

Sutton & Beaumont, 1989: Formerly confined to vice-counties 61 and 62, this species has moved west in recent years and is now found as far over as the Harrogate district and middle Wharfedale in VC64.

2012 (CHF): Fairly widespread now across all five vice-counties and possibly under-recorded due to confusion with similar species such as Grey Pug and White-spotted Pug. The second generation in late July/early August has grown in size to outnumber the first generation. Worn specimens and melanics need dissection - the asymmetrical ventral plate is very distinctive.
