Hello,
This long-legged Dipter has curious eyes, which are joined behind the antennas, if I see correctly.
Any idea ?
#3
Perhaps
Trichinomyia flavipes.

See for real Trichinomyia flavipes Black's post on 21-08-2007 19:43.

On Black's pictures, the legs are clearly yellow or even transparent.
The back legs are clearly black in my case. For the forelegs, it must be an artifact of the sun (backlighting).

Well, maybe a
Trichina rather than a
Trichinomyia? Igor?

Rhamphomyia (Empididae)?
Too bad the wing venation of badly out of focus.

Hello,
I have another picture. I'll check whether the wing veination is clearer.
#10
I think in
Rhamphomyia the way the eyes meet on the frons would be different (for xample, over a shorter distance) and that we would be able to see something of the rostrum (not here) and that we would see some longer setae on the legs.

I notice that a copy of this pic in the Gallery has been identified as Trichinomyia by Igor. No, not that Igor, the other Igor

Hello,
Well, sorry, nothing better about the wing.

Dear Pierre,
The size of this fly is a bit strange (8 mm). Is it correct? I do not know any Trichinomyia, Trichina or Holoclera (that this fly really resembles) with such a big size. The wing venation would be best solution but some other structures could also be helpful. So, maybe you could post your second image?

Dear Igor,
About the size: it may be over-estimated. Maybe 5-7mm would be more correct. I'll post below a photo of the whole leaf. Maybe someone will recognize the plant and know what is the size of the "peaks".
I post below the other photo.
I hope it can help.

Here is the other photo.
Thinking twice about it, I thinkthis was a hazeltree.

To me it has the 'jiz' of Rhamphomyia subgenus Holoclera. But:- so many characters can't be seen well in the image. I can't see anything of the mouthparts and presume they are hidden in this view. Also, I think(?) I can make out acr setae which would rule out the obvious Holoclera
cheers

How about
Bicellaria?

Know what you mean but the legs are quite slender and with weak chaetae so it would probably have to be B. simplicipes. In Bicellaria the thorax is rather strongly (often very strongly) arched and this is clearly not the case in this image.
Also, to best of my knowledge there are not any European Bicellaria with paler bases to the legs (but I may be wrong).
If I noticed it in a British woodland I would call it R. nigripennis
cheers

Hi Adrian,
This is not R. nigripennis. I have some doubts about the genus of this image but enyway it may be something undescribed that is not too big surprise for the region it was taken.
All the best,
Igor

Well, even if we end with a question mark as identification, this was an interesting thread...
Thanks to all.
