– Significant Record / Rare / Vagrant
– care required in the identification process, as confusion with similar species is likely – quality photographs required.
Confusion Species: No similar Derbyshire species
A very rare species, thought to be possibly extinct in the county or only holding on in a very isolated population, such as in Dovedale where it was last recorded in 2011. It is predominantly a moorland species.
First recorded in 1866 from an undetermined site in Findern. By 1986 only four records were known, with the last one being recorded in 1975. Since only four records of 5 individuals all recorded from Dovedale by the same recorder. Two in 2010 and two in 2011.
An adult was attracted to light at Glossop on 16/8/2026 and recorded by Christian Heintzen, resurrecting this species and putting it truly back on the Derbyshire Map, after an absence of 15 years.

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.
