I found this Tachinidae in a yellow pan trap in April 2020. I tried to key it with Tschornig, but I get stuck at species which are not correct. Which genus or species could this be? I can add additional images if necessary.

Thanks for any reply

It is a Blondeliini. Oswaldia ?

Thank you for your reply. I keyed it again with Tschornig. I went wrong with the shape of the calyptra, the outer edge should not be convex for Blondeliini. It now keys to Oswaldia muscaria.

That feature is very difficult to understand if you have never seen and completely obvious when you have.
Rest assured that Ethylini (those with the weird calypter) are very rare in lowland temperature Europe, so you can fill in β€œno”. for β€œall”. cases πŸ˜‹

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

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

No idea what happened but it is corrected
