At first glance, both sexes resemble Blue-tailed Damselfly rather than other Coenagrion species. The pale brown pterostigma is longer than in other Coenagrion species.
The male has no ante-humeral stripes and a black abdomen except for blue markings on S1-3 and S8-9. The anal appendages are particularly long.
The female has greenish ante-humeral stripes and markings on S1-2 and S9 similar to the male.


Open but well-vegetated waters. It can tolerate some salinity.
