When I look at this I think Muscidae but then shouldn't there be at least a little bend of that vein to the tip of the wing? And then if scathophagidae there should be another cross vein I also can't see ...
ok, you can laugh, I know I need help :D

BTW, my book goes on talking about veins 1, 2, 3, 4 ... and that is not the way people is talking here! Can you suggest a place to see a translation and which vein is which? :)
