Common blue damselfly  (Enallagma cyathigerum)

Common blue damselflies are found across most of the UK, and are probably the most widespread member of the ‘blue’ damselflies. It is also one of only two species of damselfly that can be found in both Europe and North America, its range almost completely circling the Northern Hemisphere.

This species is found around open lakes and ponds, along river and canal banks, and streams, provided there is plenty of bankside vegetation.
