Thread subject: Diptera.info :: Odinia boletina <- flies with strong legs on Polypore

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,

Ectemnius
