** This page is to record aggregated records only – see individual species pages for additional information. **
ID Difficulty:  Red – difficult to identify – detailed examination required, often a Gen Det and/or specimen and quality photographs are required.
Confusion Species:  Euxoa obelisca – Square-spot Dart; Euxoa tritici – White-line Dart
Distribution:  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.
