Gnophomyia viridipennis?
Hi
Does anyone have an image of this species, dead or alive, that they can post?
I've run to this conclusion in the key (Stubbs, in prep.) but have no idea what it looks like and I am fairly new to crane-flies. Cannot find an image online.
Individual female taken in Shepperton, VC21, 10.ix.2008. in urban fringe woodland beside slow flowing stream.
I would post an image but I've lost my usb camera lead.
Thanks

I think I've got a female that I could photograh for you tomorrow, Scotty. What gender is your specimen? The larvae live under the bark of fallen, rotting black poplar trees. Was there one nearby?? John K

Re: Gnophomyia viridipennis?
Hi John
The specimen is female. There were plenty of Populus and Salix species in the vicinity. Possibly P.canescens but it is an urban site with many non-natives planted. Falk (1991) does not suggest that the P.nigra association is exclusive.
In broadly descriptive terms my specimen is largely black. The wings are clear with a hint of smokiness about the stigma and the veins at the extreme base are rather pale. The legs are black except for the extreme base of all femur, which is yellow/orange. The tips of the halteres are of vibrant yellow. The upwardly curved ovipositor is dusky orange with darker areas.
Hope this helps and thanks for getting back.
Scotty

I have some photos of mounted male and female of this species, reared from under dead poplar bark and named by Alan. Would this save you some time, John?

Hi Judy
I neglected to mention that John very kindly sent me an image offline. I'm sure that they would look great in the gallery! A great reference for fledgling dipterists.
Regards
Scotty

Photos of the male and female are now in the gallery. Not the best quality, but most of the features you mentioned in your post above are visible!
