Quite small, caught in light trap. Placed on leaf by me.
No interactions present.
Can you be more precise about the size?
Although I agreed with your ID I've had another look and think it might be Great Dart which is about the same size as a Heart & Dart. White-line Dart is a bit smaller.
Thanks for your input. My field guide (Paul Waring and Martin Townsend) shows two illustration of a Great Dart. One is just slightly larger that the White-line and the other is slightly bigger that the Heart and Dart. All a bit confusing! But having had a closer look I think it could well be the Great Dart (at least the smaller version). Thanks again.
Also, your photo shows feathered antennae which WLD doesn't have but GD does. I'll remove my agreement and add Great Dart.
Excellent moths you're getting - keep them coming.
