Again, not sure what it is (!), but Pollenia are not usually taken to species from a photo.

Not Pollenia, but maybe Polietes.
You should add that as an ID, it is more likely than the ID given.
I suggested Polietes, but not as a certainty. If I am to be cited as the source it should be with a large degree of doubt.
That is my fault, for suggesting that you add Polietes as it was closer than the ID given. notpop has picked up on that and added it himself.
It could be right, I agree, but maybe not with 100% certainty! 'It might be' would have been better, but until an expert comes along, Polietes is a starter...
