Status & Distribution
Very common throughout the British Isles except the northern half of Scotland.
This species is easily confused with the other members of the genus Coenagrion and with the Common Blue Damselfly Enallagma cyathigerum . Look at S2 (on the males) for distinguishing characters. The females can be particularly tricky to distinguish apart.
