The most common Cylindromyia with discal bristles on the abdomen is C. interrupta. C. auriceps lacks discals.

auriceps: abdomen usually with discal bristles.
interrupta: Apical scutellar bristles missing.
auriceps: Crossed apical bristles present.
I can´t see if there are apicals or not.

All three photos of auriceps in the gallery (possibly only two specimens) lack discal bristles.

I think I see small, crossed apical bristles on the scutellum.

Yes, I know about the gallery. I can´t say I know, Just read it here.

* discals are variable in auriceps
* thoracic colour pattern does not fit auriceps.
* given the size of the flowers, your '13 mm.' must be off. It is a lot smaller
* what looks like apical scutellar bristles, seems much too large for these. So I am thinking, it might be something else.

* all in all, I am not certain. Either a auriceps with peculiar light or a interrupta with pseudo-apicals.

Hallo, Can the enlargement help? I think 13mm is a bit too big, more like 10mm, measured by the flowers.

So the apicals are present and small. Auricps, after all.

Hi Theo, I understand that correctly, it is C. auriceps.
