[4] Mature adults differ from most other blue damselflies in having expanded white edges to the tibiae, paired black markings down most of the abdomen, broad pale brown double antehumeral stripes, wider head and a pale brown pterostigmata.

This species favours unshaded slow-flowing sections of muddy rivers with abundant floating vegetation.

It also occurs in muddy streams but is rare in lakes or ponds of any sort.

[4] Elongated eggs are laid whilst in tandem, into emergent stems and especially the underside of floating leaves.

After emerging, adults tend to congregate in the shelter of tall vegetation, although some immatures wander away from water and have been found five kilometres away from the nearest breeding site.
