Distribution: (First record: August 2012 at Kings Newton ) – (Last record: 2 August 2022 at Belper ) – Not listed in Harrison & Sterling (1988). Possibly a new species for Derbyshire (this specimen was trapped in August 2012). Seems to be expanding its range but described as a local species in Britain.Maybe a possible immigrant.

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.
