The color of the basicosta is helpful with Lucilia but not Pollenia. The basicosta of the rudis group can be yellow, brown or dark brown/black. I have yellow and black from two different rudis specimens. According to Dr. Rognes, the features mentioned in his publications have "no taxonomical value." In other words, the features are unreliable.

The photos here depict a species of the rudis group in my opinion. I cannot see golden vestiture which can rule out angustigena. Notice that t2 has 2 ad setae.

I'm very comfortable suggesting a male Pollenia rudis.
