Hi,
Strange summer, a second very characteristic but completely odd species! Caught from a powerline in South-Central Finland 19th of July.
Looks superficially like
Gonia picea, but only few hairs at r-m, basicosta and tegula black AND of course phenology obviously different.
In the Central European key this keys as
Onychogonia (silver pollination on cheeks more obvious than in the pictures), unfortunately it's a female, but superficially
O. cervini would fit but as all the
Onychogonia seem to be high mountain species (in Finland O.flaviceps occurs only above tree-line in Lappland), so nothing makes much sense. With Bei-Bienko this keys as
flaviceps... Anything obvious that I miss here??:o
Got my first
Leskia aurea from the same site... been a real struggle to get this fairly common species.:D

Sorry for the quality, still lacking a proper scope camera...

If it turns out to be that species then it's a great find - well done! :D
Leskia aurea ... common?!! ... :o ... (sigh)

Well, common is relative... I've seen quite many specimens collected by others. I've also tried rearing it from
Synanthedon spheciformis, but unsuccessfully. It's widely spread and visits flowers, so makes the odds good!
Nice photo, Jorge! A really beautiful species.

I must admit that collecting in Europe and seeing all the wonderful species you have commonly really makes me despair when I collect in the British countryside. We have a fairly good species-list but the numbers of insects and the diversity around me seems to get worse and worse each year. :( The last 3 summers have been very cold, wet and windy, which doesn't help.

There are 3 very similar species of Onychogonia.
Flaviceps being the 'least' boreamountaineous.
I'd really need to see the specimen to say more.
I have 2 species in my collection for comparison.

Sorry! I had a slow connection earlier, so I didn't actually have time to check... :| Anyways, my hunch was right. Beautiful pictures!:D

Thanks Theo! I will e-mail you.
I wonder what is the "flaviceps" part in these black-legged flies?
