Not a great shot this one (I couldn't get close enough in time) but I wondered if anyone out there could help with an ID on this damselfly. I've checked my books and the British Dragonfly Society galleries, but am still stuck. It was flitting around over brambles, nettles and the occasional thistle and what doesn't come across in the picture is that the wings were almost totally translucent and silver. Thanks in advance.
