I am stymied on this one. Found - but not retained - in Scotland last week (grid ref NN576334). The closest I can get is Atherix ibis, but not every feature seems to fit. Help please.

Plainly I have a problem attaching pictures - both the jpgs I wished to post are well under 15k and neither has any gaps in the filename on my computer.

Hello Anthony Bainbridge,

It's another, closely related family: Rhagionidae. Rhagio scolopaceus, female.

Regards,

Ectemnius

Thank you - is any confusion possible with R. strigosus

R. strigosus has yellow pleurae, of which there's an indication in your specimen, but the frons should be much narrower. Most of the British records of strigosus are from the chalk, so that wouldn't fit with your Scottish site either. I think this is most likely a slightly teneral scolopaceus, but the wing looks rather broad (could just be foreshortening), and I'm wondering whether it could be latipennis? It would be interesting to hear other views on this, from those who are familiar with that species.

Hi Tony,

You missed our very recent review of this group. Pleura are totally unreliable.
This is not strigosus.
I can see you are thinking of latipennis, but this species has never been seen west of Osnabruck and the picture is simply not good enough to reach such a firm conclusion.
So, to me it is female scolopaceus, untill we get better pictures.

Theo

Thanks to all for their help. I agree R. scolopaceus - I have no better picture.
