I was throwing some weeds in the green wheelie bin when I saw something flitting across the corner of my eye. To my surprise it was a damselfly which landed on a nearby length of old branch which was propped up against the fence. A good job the Nikon is usually in my shirt pocket just in case something interesting pops into view. It wasn't at all bothered as I gradually got the lens closer and closer.
As far as I can tell it is one of several forms of female Blue-tailed Damselfly, maybe infuscans.
