Hello Carnifex, that is definitely golden. I don't know why because, as a Bellardia, it keys to pandia/viarum. Anyway, genitalia are much easier with Bellardia. We don't need a dissection. Just a dorsal view of cerci/surstyli.

I started studying diptera with a cheap led microscope and i couldn't dissect under that lens. I just used reading glasses to see and a fine needle to tease or pry out the cerci/sursty;i. It doesn't work with Pollenia but Bellardia are quite different, so a simple view will make determination a breeze. You may be correct with pandia but it looks strange. I lean more to viarum despite the pv on t1. Calliphoridae can be difficult.

Best wishes,
John
