Hello Lorin,

I've keyed this to the rudis group. I exclude hungarica for a few reasons but mainly because of the strongly curved lateral sacs. Thus, we are left with angustigena and rudis. It is complicated now because many features really are unreliable. golden hairs would indicate angustigena but there should be more of them and i am not convinced that it isn't a lighting effect. In photo 1, i see no golden hairs on either femora t2 or t3. Despite any golden hairs, angustigena usually only has one ad on the mid tibia. Your speciman has two ad. I think that it is easier to find a rudis with a few golden hairs (i have two specimens with this feature) than it is to find angustigena with more than one ad. I suggest that you stick with Pollenia cf rudis female.

"careful observation and adequate lighting conditions are necessary, as it is not always easy to appreciate colour of hairs as distinct from colour of light reflected from them" - Dr. Rognes

In the future, you are welcome to send Pollenia specimens to me for examination. I really don't mind. I love Pollenia. I am happy to help. Keep this in mind.

Best wishes,
John
