White-line Dart
Euxoa tritici
Species account (old)
Well distributed among all the coastal sandhills in a variety of forms, this being one of the most variable of British noctuid moths. [...] In Durham it is still found along the sandy coasts around Hartlepool: it has also been recorded from the cliff areas of Blackhall and Denemouth, Harden. The inland dark form is found only rarely, but has been seen at Shildon and at High Spen. The moth is on the wing from about early July to early September, often in large numbers in its chosen haunts. It is perhaps the most likely of the coastal noctuids to be encountered on herbage (usually Ragwort blossom) by day.
