Prey.
Prey is actually a species of Nomada (cuckoo bee). Good for size comparison. Now I know the fly is not as big as I thought initially:-)

Excellent
See the other shot of the male from Okanagan valley for comments. This is likely the female of the undescribed species as it also has the golden occipital hairs.
