If it has a bundle of very small pale hairs at the junction of the humeral crossvein and subcosta on the underside of the wing, then I see no reason why it shouldn't be.
This minute bundle of hairs gives away the species, which is kind of nice since female Pollenia sp. otherwise are notoriously hard to determine.
But look carefully - these hairs are easy to miss!

Hi Walter - I've looked under my microscope, which is only 20x magnification, but I can definitely see (if I look at the right angle) some fine pale hairs on the underside of the node. :)
