Beautiful Demoiselle Calopteryx virgo
Took this back in June and posted a
photo of the female that I'd taken at the same time, but for some reason didn't get around to posting the male.
Actually I found a couple of these in the brook that runs through the village. Unfortunately a few days later we had major floods so I don't know whether they've managed to establish themselves there, but they do seem to bbe moving outwards from the original colony down through the Leam.
