All requests are from the urban area of Vienna, if not otherwise stated.

My Diptera observations (and other living forms) can be found here, and corrections or comments over there would also be appreciated.

Definitely a Sarc, I think Ptychoneura.

Can’t be. Ptychoneura is a cleptoparasite of stem-breeding Aculeata.

Yes, I read that too - I guess I will have to make more photos, of the head especially.

Also, originally described by Fallén and Meigen as 'Tachina', so I am in good company Grin

I’d like to see the abdomen from above and obliquely behind (say, 45 degrees angle)

Maybe it is better to use Oebalia instead of Ptychoneura, it is a matter of opinion.

This is Oe. cylindrica.

The photo of the head profile shows a row of bristles running down the parafacials. Wouldn't this exclude Obealia/Ptychoneura?
Could Metopia also be an option?

It is difficult to see, maybe I overlooked those. It is possible to give a better view .

Thanks

Apologies, at the time of posting, I did not know what features to focus on, so the bristles are hardly visible.

Irrespective of the final ID, still wondering about the phenology (occurence in February!)

The phenology is off in any case. If it is Metopia, it is likely campestris, which I have never seen earlier than end of April.

It seems to be Metopia grandii. No anteroventral bristle on the mid tibia. Unless I missed something, this would be a first for Austria

Of course ! Marginals on syntergite 1&2 are lacking ! Metopia grandii male it is.
Please change the title of this thread, so that we are able to find it.

Theo, thanks for this fruitful discussion.
One last question, how to determine the gender here?
This species doesn't show the flashy parafacials as other species of the genus

Well, it is a guess, based on length of third antennal segment, shape of abdominal tip and of course date (males are earlier)

How do I submit photos for identification

@beateSenf you can check the coincident threads with your species and try to write to whom identified them

No worries. Not everyone has time all the time. Wink

Hallo, I have a question. Are there any hidden rules in this forum? Do you have to upload spectacular flies to get answers? As soon as the inquiries slide to page two or further, they rest gently

21.01.21 08:58
No idea what happened but it is corrected

my portrait in portrait format is squashed into landscape format. how can I prevent that next time? Greetings Beate
