Found that male Calliphoridae this morning on the compost (Ansbach, close to Frankenhoehe Nature Park, old deciduous forest, 2021-11-10).
I think it's a Calliphora but it seems strange to me:
- size > 10 mm
- abdomen green
- parafacialia fine hairs on upper half (if at all)
- orange hairs on postgena
- basicosta black
- anterior spiracle dark
- veins darkened
Can it be loewi?

Good question: I thought, Onesia should have hairy parafacialia like Bellardia, but that was an error! The prest ia is weak and the post ia seem to be partly broken. Onesia is it (though I fear I must not call it floralis)!

Thank you very much, Theo!

Yes, but that soecies does not occur in this region

Hopefully I may call it floralis as I've found evidence in my images using
Revision der Gattung Onesia (H. Schumann) - loosely translated:
"Crucial is also the distance between the compound eyes of the males: it's narrowest distance is longer than the distance between the hind ocelli"

and another one:
"Important is the male's absence of the ventral bristle on the mid tibia"

@EsinM: Thank you! I've excluded Calliphora subalpina as it should have more marginal scutellars.

I have some very similar copies, I can send them along with the flies for Theo. Or I can take a photo. It's very interesting to find out who it is. Such flies are very active in autumn near beer traps.

Your fly looks very similar to my Onesia - except the very blue colour of the abdomen and I'm not sure if there are 3 postsutural ia. But I couldn't find a Calliphora with dark basicosta, gena and a resembling frons - loewia's is narrower.

Oh, you got it pinned !
Simply check the number of post IA bristles.
Or make a sharp pic of the thorax.

I mentioned before that none of the exernal featues by Schumann work in mu material ( well, they work 75 %)

Thanks Theo, I remember your words about Schumann

The pinned fly is from EsinM, Mordovia reserve, it resembles my fly.
