You might take a look at this one: http://www.diptera.info/forum/viewthread.php?thread_id=31119
I used a NB! Dutch key and then it COULD be
Cyrtopogon lateralis
But i think it should be confirmed.

Oh You have right, it looks it is a Cyrtopogon lateralis. I forgot to write where the picture is taken, middle of Sweden..
Thank you very much for your help :-) it's not easy with Diptera to find right..
have a nice evening
