This fly was about 11 mm. Suillia but is it affinis?

difficult to say. Arista is rather pubescense than plumose.
Maybe do you have a better pic ?

I agree that beause of the bare-looking arista this doesn't seem to be affinis, but some other Suillia instead. 11 mm sounds quite large!

(By the way, I just 15 min ago checked an affinis reared from truffel mushrooms found under the earth surface in southern Finland.

Andrzej or others, do you know if this is new ecological data for the genus Suillia?

Beg your pardon Kurt for a slight off-topic...)

Thanks to Andrezj and KWQ for looking at my pictures.
Here comes a close up of head from two pictures.

Definitely not an affinis as already presumed, it has a distiinctly longer plumosity of arista. If you were really interested in finding the right species you would have to present some more pictures though (mesopleuron, scutellum from backwards etc.)
