hi flyforum,

I think this fly could be Phaonia (rufiventris?)
But I can need some help..

Hello, Robert!



I think that is Phaonia subventa. It's by far the most numerous fly in our garden, at our house, at the forest... here in the last weeks.

Besides the other differences (scutellum not all red for example) I notice, that the colouration of the abdomen is mostly paler orange than in P. rufiventris.

I agree with Juergen - we can see about 10-11 frontals setae.

Thank you very much Juergen and Nikita,

I thought P. subventa was more a spring-Phaonia ?
Looking at the thorax, scutellum and abdomen I see some whitish dust on the fly (kind of line)

Robert, Ph.subventa and Ph.rufiventris aren't "good" species, male genitalia looks rather alike.
Zaitsev key:
Ph.subventa - 2 prst dc, antenna all black
Ph.rufiventris - 1 prst dc, ant 1,2 segm. yellowish-broun
Yours - 1,5 dc, ant 1,2 segm. yellowish-broun.
Gregor at all key:
Ph.subventa - at least 7 frontals
Ph.rufiventris - at most 6 frontals
Yours - 10-11 frontals
