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:  Lead Belle
ID pointers: Confusion species is the Lead Belle and sometimes the two species are indistinguishable. One of the best ID features is the shape and position of the discal spot – small and rounded in the July Belle (luridata) and “Tear Drop” shaped in the Lead Belle (mucronata). Although this character is not always helpful, it is a good guider, along with flight period and the zig-zag outer most cross-line is usually faint. 
Distribution:  (Last record: 31 July 2020 at Hathersage )  –  A resident species, widely distributed and fairly uncommon at a local level, but scarce to absent in the south of the county. Is most likely to be encountered in the northern half of Derbyshire. Not many records or reports. Last recorded from Kelstedge in August 2013.

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.
