hi flyforum,

Yesterday I found many of these Calliphorodae sp. in the edge of the Amsterdam forest.

I don't think it is Pollenia sp. and C. vicina is also no option..

what else?

Typical was the wide-spreading of the wings, almost by al flies which I found.

Pollenia sp male.

As Gabor says, it has to be Pollenia - you can see small golden hairs on the thorax and the general shape and abdomen pattern is also quite distinctive :)

---

thank you Xespok and Chris for your reaction.

I didn't think of Pollenia, all the flies I watched didn't have golden hairs on the thorax..

Looking at the Calliphoridae above, I cannot find the golden hairs..

But generaly, I share the idea - This is Pollenia -
The eyes are also a bit brownish, which I find also in other Pollenia's

They're there if you know where to look ;) In older specimens they are often rubbed off on top of the thorax and so the sides are the best areas in live specimens. In this photo you can make out just a few small, wavy bright bits on top of the thorax (scattered randomly between the black hairs) - those are what's left of the golden curly hairs :)

Yes, I found some of these hairs.

Typical that all the flies I watched where so little blondish hairy.
