This is a species of Scaptomyza, probably S. graminum. They are a group of the Drosophilidae with leafmining larvae. The most common species of that group is S. pallida. That can be recognised by having two rows of acrostichal setae on the mesonotum. These would be running along the edges of the brown median stripe. Here you can see one extra row on of small setae each side of that median stripe. S. graminum is then the most common of of the dark-bodied species.

Thanks a lot Paul. A quite abundant species among sweeping collections, with typical long wings. That was the first time I managed to take some pictures of acceptable quality. |

I would only take it as far as Scaptomyza. There are several species like this and they can only be identified from male genitalia. At least in Finland S. graminum is the least common Scaptomyza. The less known species S. montana Wheeler and S. teinoptera Hackman are often numerous.
