Stony Stratford, Bucks.
This afternoon I managed to get a side-on shot of the barkfly I posted about 10 days ago (Jason G. had requested side view), see:
Unidentified white-necked barkfly
Well I can't guarantee it's
exactly the same individual
, only that it was on the fence right next to the gate where I photographed the last one. I also have a dorsal shot of this second individual which is pretty much indistinguishable from the first one and I have no doubts about it being the same species. For convenience I've also shown the previous image below:
