Saw this in Kensington Gardens London yesterday, in the Italian water gardens at Lancaster gate
Later - reliably informed this is a damselfly, not a dragonfly. Thought it looked a bit small. My bad.

Not quite as sharp as I would like since the lens had slight fungus - I was testing it before selling it. Sigma 75-300 AF APO on Nikon D70
