In the summer, a large number of Blue Riverdamsels are competing for a good perching position with other damselflies. The male of this damselfly is brightly blue in colour with black pattern on his abdomen. Its head, face, and eyes are also blue. Pseudagrion microcephalum looks similar to the the Common Bluetail and the Eastern Billabongfly. The female is blue-grey to grey-green in colour.

They lay their eggs in the plants under the surface of water. Females have a blade-like ovipositor for making an opening in the plant for her eggs. They will sometimes lay eggs alone without the male in tandem position.
