Hello,

finally I managed to get a picture of one of these annoying flies, after it landed on my trousers. But the picture isn't at all good.:| On a second, even worse one, I could see some orange at the side of the abdomen. Is it possible to tell more than just Chrysops sp. after this photo, perhaps from the spot on the eyes. I found they match C. caecutiens, but also other species have yellow eyes with black spots...

At forest border northwest Germany.
