Ukraine, Rivne region, on March 23.
There is a weak version that it is Hydrotaea, but I'm not sure. It is probably impossible to determine the species ...
Hi Victor, it's another male Pollenia who's lost his hair (like me...). It has a dark basicosta and distance between the eyes is approx. like the width of the flagellum. It's probalbly a Pollenia cf. labialis.
