Yorkshire Status: Fairly common and widespread resident.

This is one of those species where you need to "get your eye in" as it can be tricky unless you are familiar with it. It is easy to confuses it with similar species flying at the same time such as Grey Pug and White-spotted Pug. Worn specimens and melanics need dissection - the asymmetrical ventral plate of the male is very distinctive. It seems to be doing well in the county and nationally is expanding its range. It is much rarer in the south and east of England. The discal spot is fairly prominent and there tends to be prominent "chequering" along the veins. There is a thoracic spot, and often a quite prominent tornal spot but it generally not as "spotty" as White-spotted Pug. The second generation in late July/early August has grown in size to outnumber the first generation. It seems to be doing well in the county and appears to have been less common in Porritt's day.

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.
