Could this one perhaps be Ctenophora festiva? Photographed at the Bergherbos, Montferland, Netherlands in May 2006.

Thanks in advance.

Yes, it keys out as C. flaveolata with key in EB 66(5), 2006! :)
A female, though that is not so obvious from this angle, but the antennae are very small.

Btw, to use the key properly, you would need details of the antennae.

Ah, so it's flaveolata. I will try to get that key, it seems to work well! ;)
Thanks again for your help, Louis!

Not sure about this :o - in the UK at least, C. flaveolata has clear wings, and your photo appears to show a blackish patch towards the end of the wing. In Alan Stubbs' UK key this would mean it must be C. ornata, and would rule out C. flaveolata, so there seems to be some conflict in the keys.

I've only ever seen males of both flaveolata and ornata, so can't comment on how good a match your female is. Also, C. festiva is not in the UK (we have only three species of Ctenophora :(), so you'll need advice from others.

Look forward to hearing what others think!

I've just done a quick search on the web for C. festiva, and the images this produces do seem to match yours better than flaveolata, so my vote goes for festiva (assuming the web images are correctly identified of course ;)).

Oops, oops, sorry for the confusion : I see I wrote flaveolata, but I meant to say FESTIVA !! It really keys out as festiva in Oosterbroek et al. 2006, and matches the picture of festiva therein.

That means we all agree on festiva and both keys work properly! :)
Then festiva it is. Louis and Martin, many thanks for your help!
And a merry xmas to all of you.
