– easy to identify, generally distinctive and unlikely to be confused with other species.ID pointers: Forewing reddish-brown to orangey-brown, variably speckled black, with narrow white cross-bands or spots. Very attractively marked.
Distribution: (First record: 1949 ) – (Last record: 3 September 2023 at Buxton ) – Status uncertain – one record in Harrison & Sterling -1949. Since 2011 there have been five records, then two other records in 2023 from the north of the county. Would expect it to be common on the heather moorlands of Derbyshire. Most probably under-recorded.

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.
