Odinia of the Odiniidae. Let's wait for Jan Willem, he might be able to put a name on.

I totally agree with Paul that this is a specimen of the genus
Odinia. But it is very optimistic of Paul to think I might be able to put a name on your specimen. It is hard enough to identify odiniids when you have the specimen under your microscope:(. Some people think that a revision of the genus is needed before any new species are described. So if you find odiniids again, please collect the specimens. They are not very common in collections for as far as I know, although less uncommon than this suggests.

Odinia ornata ... or
O. rossi, but I suspect these two are synonymous.

Hi Kahis,
You seem rather sure. I certainly don't say you are wrong, but how can you be sure about this identification? I would like to hear what Iain has to say about this specimen.

Thanks a lot Paul, Jan Willem and Jere. The fly's collected, I saw the same or very similar earlier on fallen aspen. It moves very typically, with short quick dashes, quite unlike any
Lauxaniidae (actually I was rather suspicious from the start), and is not too willing to fly.
P.S. Maybe other/more detailed views would be helpful (I have plenty of them).

Well, I have spent a few weeks this year reading through most of the odinid literature, checking the identifications of all Finnish material (and Black isn't that far away), taking notes on the biology of various species etc. for a review of the Finnish fauna. I have also discussed the identification problems with Iain and Steve Gaimari.
So, I think I am right ;)
PS. The only thing I have
not done is seeing the types. The type of
O. ornata should be in St. Petersburg.

OK Jere, then I trust your judgement:). So Dima, you can change the subject of this thread to
Odinia ornata.

Yesterday caught five more on the same tree. Two of them were even smaller, around 3 mm.

My experience with Odiniidae (not that I have much) is that there is a lot of intraspecific variation in size.

Aye, that is the case.

Observed on June 13, 2010, on partially burnt bark of
Pinus sylvestris, egg-laying, from the base of the tree and at the height of up to 4 feet, 6 females collected. I examined neighbouring pine trees in same condition but couldn't find any of these, maybe they need mycelium of some specific fungus.
