– Rare / Uncommon / Scarce
– difficult to identify – detailed examination required, often a Gen Det and/or specimen and quality photographs are required.Confusion Species: Fletcher’s Pug, Grey Pug
ID pointers: A tricky Eupithecia species to identify, especially when worn. Fresh individuals are usually accepted by county moth recorders, even more so if supported with a photograph, but when worn they would require a Gen Det to get accepted. Normally on fresh specimens, the cross-lines preceding and succeeding the discal spot, are acutely angular. There is also a white spot or crest on the back of the thorax. These two features help to separate it from Fletcher’s Pug. The wing tips are more pointed in Larch Pug, more rounded in Grey & Fletcher’s Pug.
Distribution: (Last record: 13 July 2025 at Longdendale (Torside) ) – Uncommon and locally distributed in Derbyshire. Very few county records of this species. Last recorded in 2022 from Findern, which was the first since one in 2009 and one in 2005. One from Longdendale July 2025.

This chart summarises all available historical occurrence records collated by ISO week of the year. It reflects recorder effort and sampling distribution as well as true biological activity, and should be interpreted as an indicative pattern of seasonal occurrence rather than a statistically controlled abundance or phenology model.

Bedrock Geology ** indirectly affects moth distribution by influencing the type of habitat and food plants available in an area. In turn, this may affect the types of moths that can thrive, or where they can most likely be found.
