Myennis males tend to congregate on bracket fungi (presumably for display purposes) and are not hard to catch, since they generally come back if you miss first time. They do this on the upper surface, whilst the odiniids do the same underneath (only Odinia boletina in fact).

Myennis octopynctata is the commonest Ulidiids, whose larvae libe under the bark of poplars. There is also Paratephritis corticalis in the North (Norway, Denmark, Russia) and recently unintetionally introduced Callopistromyia from the North America, in Germany & Switzerland.
