Green –  Rare / Uncommon / Scarce   
Taxonomy:   Macro   >>  Geometridae  >> Larentiinae
ID Difficulty:  amber  – care required in the identification process, as confusion with similar species is likely – quality photographs required.
Confusion Species:  Other Pugs (Eupithecia spp.)
ID pointers: A reddish band at the base of the abdomen helps to identify this small, otherwise grey-brown pug. Rather nondescript in markings with faint cross-lines and a weak, sometimes absent, discal spot.
Distribution:  (Last record: 2024 )  –  A resident but locally distributed and uncommon in Derbyshire. It was once widespread in the county, but in 1986 was only known from one site situated in the south of the county. During 2008 it was being reported from an area around Carsington Reservoir and may well be spreading from that area, hence the below record from Belper, during August 2013, an unusual date.

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.
