Species Account

Sutton & Beaumont, 1989: Recorded sparsely from all five vice-counties. Most records come from VC63, where it is common in the south and VC64, although it is also said to be common at Wass (VC62) (AMRH pers. comm.). It is probably much more generally common but, as with most pugs, under-recorded.

2012 (CHF): Well-distributed across the whole county. Sometimes confused with Currant Pug which is smaller but can have very similar markings. Most years we receive reports of smaller greyer specimens from upland areas submitted as Ling Pug. This was considered by many to be a separate species (B&F 1831) but the consensus of opinion is that this is an upland form of Wormwood Pug (see Riley and Prior). The genitalia are indistinguishable.
