In the male, S2 usually has a small crescent shaped dark spot flanked by two black lines. S8 and S9 are blue except for 2 small black spots on each. The black markings are fairly extensive giving the damselfly a dark appearance.
The female is apple green and black but with blue markings on S8-10.
Clean, shallow ponds and lakes in Ireland often with floating ponweed and water lilies.
Status & Distribution
Scarce and local in Ireland but widespread in northern Europe.
*** The map below does not currently show Irish records. ***
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.
