Clean, shallow ponds and lakes in Ireland often with floating ponweed and water lilies.

Scarce and local in Ireland but widespread in northern Europe.

This species is easily confused with the other members of the genus Coenagrion and with the Common Blue Damselfly Enallagma cyathigerum.

To separate this species look for the following features:

• Coenagrion spur
• Male: upside-down black crescent marking on segment 2.
• Female: black spike marking on segment 8.
