I think this is a Sarcophagidae because of the plumose arista and setae in the meron. Which genus could it be? About 12mm body length.

Thanks,

Look at the wing venation. This tells you this fly is not a Sarcophagid.

Look for recent Muscid threads you'll find your genus.

It's very similar to this fly I phtographed a few days ago

The fly above is Muscina prolapsa. It is possible that the fly in the other thread is the same and it did cross my mind, but the scutellum is entirely orange in that fly, whereas Muscina just has the tip orange. I think your other fly is probably Mydaea or perhaps Phaonia.

Another clue about the fly above is the gentle bend in the M vein. The fly in the other thread does not appear to have this, although the angle is not ideal for being sure.

Thank you Xespok, Rui and Susan. I thought I already knew something...

Legs are too pale for M. prolapsa, and even for M. stabulans. Actually, I doubt that it is Muscina.
Could we have a dorsal view ?

I'm afraid not, she flew away when I changed position Sad

Oops Angry Very true St?phane. So with those legs, what does that leave us with? Phaonia scutellata? (is that bristle on the hind tibia in quite the right position? - looks a bit dorsal and not posterior enough to me, but the angle could be deceptive).

If it is not a Phaonia, I'm lost. I don't think it is a Mydaea with such pronouced shifting pattern on abdomen. No more idea...Sad

Maybe this new photo can help, I think it is the same species. Sorry, no dorsal view again.

I'm not giving up on this one. Today I took two more shots of what I believe it is the same species. The wing venation is clearly seen and it really looks like Phaonia sp. Do we have a confirmation?

It is definitely a Phaonia.

I think the last fly has crash-landed Wink

Your're right - it's missing some landing gear Grin

Wow, I have discovered a new family of "crawling flies" (how do we say this in latin?), I'll be famous Grin Or maybe it is just that the creature ate too much at lunch Sad . Which means we should call it Phaonia scutellata; or maybe just Phaonia sp ?

Phaonia reptans ? Smile
More seriously, I think it is Phaonia valida.
