Brown –  Significant Record / Very Rare / Vagrant    
Taxonomy:   Macro  >>.  >>  Noctuidae  >> Noctuinae
ID Difficulty:  Red – difficult to identify – detailed examination required, often a Gen Det and/or specimen and quality photographs are required.
Confusion Species: Square-spot Dart (E.obelisca) and Coast Dart (E.cursoria).
ID pointers: Extremely variable in colour and intensity of markings. Up to six short arrow heads towards outer edge. Often shows a white or pale yellowish streak running towards apex and alongside costa with another running through centre both forming a large arrow-head.
Distribution:  (Last record: 8 September 2021 at Kings Newton )  –  Scarce and locally distributed species in Derbyshire. Up to 1986 only around 20 individuals had been recorded in the county. Only one other record reported from Kings Newton 8/9/2021. A specimen was recorded on 27th July 2022 from Newhall which could potentially have been this species. Unfortunately the photograph supplied was not of good enough quality to put the record beyond any doubt. It was sent to several experts in their field on Square-spot Dart & White-line Dart and only a 90% probability of it being a Square-spot Dart could be given. Therefore the record has to be accepted as an aggregate, with a probability of Square-spot Dart.

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.
