Similar species

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. Irish Damselfly males often rest on floating leaves. The females can be particularly tricky to distinguish apart.
