Ephydridae?

Maybe...

The pic is bad but I think that the bright colours of the fly are distinctive... can be known...

Thanks!

Not one that I've ever seen before :|
I know it seems an unlikely habitat, but I wonder whether it could be Odiniidae?

No, these usually have banded legs. I was first thinking of Leucophenga maculata but the had is not enopugh in focus to check the setae, the wing venation does not wuite seem to fit and the habitat is off.

Two votes for Odiniidae, one for Lauxaniidae and one for Ephydridae... it looks impossible!

Thanks, Steve. The species was completely unknown to me. Now I at least have the general impression. :)
