Lovely photos, again! Grin

1. looks like Phasia obesa (female) - if it has yellow hairs on the gena.
2. isn't a Phasia sp. - I think it is more like Cistogaster, Clytiomya or Eliozeta. I can't quite see if the wing is petiolate or not - can we see a photo with a clearer wing-tip? Smile

(sorry, no matter how good the photo I always seem to ask for more! Wink)

Chris, I have to disagree about first one.
My test it is male, Phasia barbifrons.

Hi Nikita, Fly-1 does have yellow haltares but it also has a lot of grey dusting on the thorax, which is more characteristic of Phasia obesa. The colour of the hairs on the gena is apparently a very good way to split obesa from barbifrons in difficult specimens Smile

Hi Chris.
I compared Black's fly my photos of Ph. obesa and Ph. barbifrons and collected Ph. barbifrons I have. My Ph. obesa has much more dusting thorax, but Ph. barbifrons has not dust at all.
So, it seems you are right, I'm wrong.

In the key it says that in Phasia barbifrons is *should* have a completely dark thorax ... but just as obesa *should* have a heavily dusted thorax there are occasions where the features are not as they should be Wink So, last week Peter Tschorsnig said this hair colour on the gena is a nice way to split off obesa from the other 2 small ones easily ... so more work for Dima Wink

Thanks Chris and Nikita (I hope you don't mind me barging in your educated dialogue Wink) - I'll check the wing-tip later.

Hello Chris,
I hope this picture would help you with the colour of hairs on genae.

Hi Dima - sorry for the delay but I missed these updates for a day or two. The Phasia is now definitely P.obesa - lovely photo of the gena Smile

I'll get back to you on the orange one Smile

I have keyed the little orange fly as best I can (using the Palearctic genera software key + the Central European key) and it comes out to Eliozeta helluo but I don't have any examples to check it against.

Perhaps you or Nikita can check Russian references to see if you can find specimens to check against. Fauna Europaea has a nice map that shows it should reach your part of the world: http://www.faunae...on1=144281

Cool

Hello Chris, could this be the same one? July 23, 2006, our town park, swept from grasses near water, size 7mm.

It certainly looks like one - but older and tatty with rubbed-off bristles on the abdomen - you can still see the bristle sockets there the marginals used to be Smile
