Hello!
I need help with the ID of this fly.
Date: 2025/05/13
Location: natural garden with small lake, Vienna Basin, Lower Austria
Size 7mm

I thought it might be Carcelia spec (Tachinidae) but then I got the suggestion that it might actually be a fly of the subfamily Miltogramminae (Sarcophagidae).
The question has remained open until now.
Can anyone resolve it?

Greetings Una

Helo Una, I think Miltogramminae is correct and it's probably a Metopia sp.

Looks like a Sarcophaga sl. to me.

Hey Una,

Interesting find! I can see why there’s confusion, it does look a bit like both. The slimmer body makes me lean toward Miltogramminae, but a clearer shot of the antennae or wings would really help confirm it.

Thank you all very much for your helpful answers!
I can understand now why this fly caused ID problems.

Re antennae and wings: Unluckily these two pictures were the only ones I was able to get. The fly was very elusive and I was not able to sight it again.

I will stick with Miltogramminae (Sarcophagidae).
I urgently needed some kind of identification for a garden biodiversity project, but for this cause the proper subfamily will suffice.
I had hoped for a Tachinidae since (understandably due to frequency of occurence ) I have documented much more Sarcophagidae but: You can´t always get what you want :-)

Thanks again and greetings!
Una
