Hi,

Is this a female Trichocera?

Trichocerid ovipositors usually curve ventrally, so I'm pretty sure this is one of the short-winged tipulids, perhaps Tipula grisescens. Can you tell us what length it was?

Hi Tony,

Sorry, app. 18 mm. Later I saw a couple (no camera at hand) copulating. Male same size with full grown wings.

It's typical of the males to be fully winged - only the females have reduced wings. I think a more likely species is Tipula autumnalis - this flies (or walks in this case!Smile) until October. (T. grisescens is normally a spring species.)
