Is it possible to say what it might be? jeremyr attached the following image: [154.49Kb] Edited by jeremyr on 30-08-2014 03:47

Lydina would have a strong pteropleural bristle with equal-sized, paired lappets on the hind spiracle Manager of the UK Species Inventory in the Angela Marmont Centre for UK Biodiversity at the Natural History Museum, London.

Neither of these have it and the antennae are thin. here's a picture from the front, and one showing more of a profile, and the best I can do on the wing, which seems to show just a few hairs cheers jeremyr attached the following image: [133.06Kb] Edited by jeremyr on 23-08-2014 00:57
