4K footage of damselflies mating on Walthamstow Marshes, London, UK - 19th June 2017.
There are several species of blue-coloured UK damselfly all similar in appearance.
From the markings on these I think they are the Common Blue Damselfly (Enallagma cyathigerum).
The male is blue and the female can also be blue or grey/light brown.

Some damselfly have elaborate courtship behaviours. Many species, like the Common Blue Damselfly are sexually dimorphic, the males often being more brightly coloured than the females. Like dragonflies, they reproduce using indirect insemination and delayed fertilisation. A mating pair form a shape known as a "heart" or "wheel", the male clasping the female at the back of the head, the female curling her abdomen down to pick up sperm from secondary genitalia at the base of the male's abdomen. The pair often remain together with the male still clasping the female while she lays eggs within the tissue of plants in or near water using a robust ovipositor.
