- difficult to identify - detailed examination required, often a Gen Det and/or specimen and quality photographs are required.Confusion Species: White-line Dart (Euxoa tritici)
ID pointers: The main confusion species is White-line Dart (Euxoa tritici). It is possible to safely identify many individuals of this species by external features, but extreme examples of White-line Dart means that where there is doubt a Gen Det would be advisable. This species has probably been overlooked due to 1) It’s similarity to White-line Dart and B)Square-spot Dart is not usually to be expected inland, being considered primarily as a coastal species. The absence of arrow-head markings on the inner-side of the outer cross-line are a good indicator.
Distribution: (Last record: 1974 ) - Current status uncertain. Possibly a rare and locally distributed species. No records since 1974. 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.
