hello flyreader,
Yesterday I found some of these flies, next to a forest on a bridge.
Most of the flies were females, quite big > 15 mm
Male (I guess same sp.) was smaller.
they got long arista(with hair) and the 4th vain in the wing is straight.
abdomen are yellowish/gold and legsparts are red/braun.
I think this is Phaonia, and perhabs it is Phaonia viarum?
Must be difficult sp. I think... B)
* pictures could be different flies, they are made on the same place and time *

Hi Robert.
By general impression fly rather looks as Anthomyiidae for me.

Looks a bit chubby for Anthomyiidae to me. I think Robert is pretty close. Is that a dorsal bristle on the hind tibia? (Sorry - still not very good at determining where exactly bristles are). Wing venation and body pattern looks right to me. I think the 6th vein probably reaches the margin.
Robert - are you sure about the size though? - way too big, for
Phaonia, Antho or
Mydaea.
[I've edited this, because just wrote a lot of rubbish, which I have now deleted - managed to look at the wrong specimen in my collection and totally confuse myself - it's a bit chaotic in my workroom at the moment]

Thank you Nikita an Suzan for your reaction.
I knew these sp. are difficult but sometimes you have to try things..
Now I can look backwards sometimes to these pictures and comments, perhabs I learn some of it.
About the size., it was a guess and it coulb be a few mm smaller..
greetings, robert

Let us say 12mm. wingspan. I haven't keyed it yet using what is visible of the chaetotaxy but this fly looks very like the two
Phaonia viarum in our collection (Ulster Museum, Belfast Ireland). Note the microscopic eye setae, red basal antennal segments,discal vein with a slight curve forward shortly after the middle of the apical segment. All characters right for
viarum as are the reddish-yellow legs, dark tarsi, and distinctive golden-yellow pollinose patterned abdomen. A heavy looking fly.Could well be Roberts perhaps (c.f.)
viarum is entirely correct :p:p I'll look in more detail later. Robert (homonym see glossary)

And I think Phaonia viarum = Phaonia valida (Harris, 1780)
