Blue Damselfly species

10th August 2025 - the surface of the lake on Granta Park seemed to be shimmering, and on closer inspection one could see that just above the surface were flying hundreds if not thousands of damselflies. At a distance they were hard to identify, but on the bank Andy M was able to pick out a mating pair of Common Blue Damselfly, and a displaying Blue-tailed Damselfly.
