Ptychopteridae in my opinion, they have a unique feature in folding their wings along the false vein - see your first photograph.

Thank you Jasen as well for additional informations.So, I'm changing titel into Ptychopteridae. Camparing pics in the "web" found this page with similar fly: http://aramel.free.fr/INSECTES15-1.shtml Could it be Ptychoptera contaminata , a male? Best regards, Brigitte |

P.contaminata I believe is a common one, but their identification is based on wing markings (better seen when fully-open) and male genitalia. Comparing photos on the 'Net is good in a lot of cases as long as the material you are using is capable and reliably-named, but when checking them you need to know what the defining characters are. The wings may match, but the genitalia may not. Try getting hold of a key relevant to your country, and see if you can get further that way

Brigitte: Hard to judge without better resolution of images, but definitely not P. contaminata: wing vein Rs is too short, cofined by a black spot and it's genitalia does not fit. Somewhere within P. lacustris-group. so long, xylo |
