I know the photos are awful, but the fly seems rather characteristic, and I can always give it a try.
Fly was rather small (4 mm?), the eyes seem to be reddish on the upper half and bright green on the lower half. Face and legs seem yellowish and wings are quite heavily spotted.

I photographed it today at Leerdam, Netherlands.

Is this Ephydridae? Could perhaps anything more be said about it?

Thank you in advance!

Why not Tephritidae? John Smit will give you the answer.

Thank you, Xespok. You are probably right. I asked John to come and have a look at it.

Hi Jan,

At first glance I'ld say Oxyna, but if you photagraphed it just recently as you told me in your e-mail, than this is impossible. In that case it should be Tephritis, which would be me second guess. But in order to tell the species I really need a better look at the wingpattern.

So thanx for the confidence Gabor, but I must pass on this one.

Hello John,

I photographed it yesterday, December 18th. So it should be Tephritis then. Unfortunately these are the only photographs I have.

Thanks very much for your help!

Hi Jan,

It was the yellowish tinge that made me think it could be Oxyna. But now having ruled this genus out, based on the datum, the only Tephritis I can think of with a similar yellowish tinge is T. bardanae. Of which the larvae live in flowerheads of Arctium.
A pitty you don't have a sideview to confirm it.

Cheers,

John

Yes, it's a pity. The most beautiful flies always seem to be the shyest :@
But it is nice to know it is probably T. bardanae.
Thanks for your help with this one!
