these two flies I found on a polypore mushroom in the Botanical Garden of Vienna.
Very conspicuous was the reflecting white face in the area of the mouthparts and their stuttering walking behavior. Reminded me of a scuttle fly, in fast forward.

Yes, Odinia is a mess but nevertheless I think your specimens are O. boletina.

There was a discussion in this forum some years ago where, according to a translation of the original description, the transverse nerves in O. boletina are not infuscated, in contrast to O. ornata. Is this still valid or obsolete?

Hi Carnifex,

The weak spots on the crossveins and the habit of sitting on the underside of a polypore funghi (probably Fomes fomentarius) all indicate O. boletina.
If you want to be sure then you have to macerate the specimens. Then the markings on the eyes will become visible. The number of eye fascia are indicative of species.

Kind regards,

Hi Carnifex,

Yes, one eye fascia -> Odinia boletina!

Kind regards,
