Opetiid Fly
Fri 2011-12-02 
On foliage near a fungus-covered log: a small black fly, probably a male Opetia nigra (Diptera: Opetiidae). O.nigra is the only UK species in the family Opetiidae, which was recently split off from the Platypezidae.
The Opetia wing-vein pattern differs from those of the Platypezidae (see here, here, here, here and here).
