– care required in the identification process, as confusion with similar species is likely – quality photographs required. Confusion Species: Treble-bar
ID pointers:
Very similar to Treble-bar but slightly smaller and the cross bands are usually paler and less intense. The tip of the abdomen is blunt. The angle of the basal cross band is usually acute, thin and sharp but can be 90° so other features need to be considered. The best way to ID this species is by looking at the tip of the abdomen which can easily be done if the moth is contained in a see through pot. A photograph of the abdomen tip should accompany the record.
Distribution: (First record: 1970 ) – (Last record: 20 September 2024 at Melbourne ) – A resident species that has become locally scarce, with most records coming from the central Derwent Valley. Once a well distributed and locally common species in Derbyshire. A recent colonist in the county with the first record in 1970. Very few records.

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.
