Dr. Rohacek has kindly confirmed that at least the fly in my picture was a
Crumomyia pedestris (Meigen, 1830) female, f. brach. He also writes, "This interestingly looking species lives in swampy habitats and its larvae usually develop in dead snail tissues. Rarely, also macropterous form can be found".
