Muscid genus

I agree it's a muscid, and on balance (e.g. the orange legs & activity during November) also that it's Phaonia (unlike the genera Helina & Mydaea, this would have a strong but hard-to-see bristle on the dorsal side of the hind tibia...). Can't identify it to species though.

Dipterists Forum

I asked members of the Dipterists Forum to look at this one and Stephane Lebrun confirms it as the muscid Phaonia tuguriorum, see:

Thanks to Stephane for the ID.

Hello What is the difference

Hello

What is the difference between the 2 species
"Martin, looks like you have already mastered the family. The only comment I would make is that the very rare P. scutellata is superficially very similar to tuguriorum, and it takes quite a lot of discipline to take a series of such a common species on the outside chance of finding the rare one"
