This is one of the species of Pug that you really need to know. "Worth learning" says our Field Guide. It occurs in a variety of habitats and has probably always been common in the county. "Common probably everywhere" proclaimed Porritt in 1883. It is often confused with Golden-rod Pug, Larch Pug, faded Green Pugs, Fletcher's Pug and almost any Pug if you are the sort of person who gets confused by Pugs. It is a fairly large species with broad roundish wings. It is as grey as its name and has fine cross lines, a small discal spot, and the hint of a tornal spot. Its main distinguishing feature is that it doesn't have any distinguishing features such as thoracic spot. Melanic forms are commonly seen. These should be dissected if you want to identify them. The thing that always strikes me is the broadness of the wings compared to the other confusion species. Numbers in the county are stable.

Sutton & Beaumont, 1989: Recorded quite widely and often frequently in VC63 and VC64, there are scattered records from the other three vice-counties and it is said to be common, especially as larvae.
