We caught this moth in Aberystwyth last night and wondered initially if it was a Square-spot Dart in view of the late flight period. The books state that the White-line Dart flies mid July to mid August. However this moth shows definite black arrow heads towards the outer edge of the fore-wing and the outer central cross line curves round and barely touches the kidney mark as described in Skinner. This suggests the White-line Dart. Any thoughts on this?

It is a White-line Dart. All recent records have been from Aberystwyth and the Dyfi area. They may be seen throughout August and we recorded 8 on a good night at Ynyslas on 3rd September two years ago.ReplyDelete
