Today I saw this rather small (say 5 mm) fly on Aegopodium podagraria. It reminded me of Solieria pacifica - but it also differs from that species.
1. In my recollection, Soliera was bigger
2. I saw Soliera end June, 1 month later than this year, while 2007 had a record hot spring. So Soliera seems to be a full summer species; to day might be too early.
3. Soliera has a uniform ground color. This fly had the same color at the abdomen, but head and thorax were greyish, giving a strong impression of separate colors for thorax and abdomen - much stronger than when you look at the photo's.
Additional info: Amstelveen, the Netherlands. Grass land with lots of flowers, pond and ditch nearby, as are shrubs and trees. Clay soil topped with sand.

Definitely a male Solieria.
Given the locality, must be pacifica.
If you can get a glimp of the tarsi....

About the date,
it is early, sure, but there have been more males in May.

I'm not really sure.
It might be vacua, which would be a spectacular find.
So probably not, I just can't see enough
