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. Northern Damselfly is a weak flyer and has a very restricted range. The females can be particularly tricky to distinguish apart.
