A female Matrona cyanoptera

This species is generally found around shallow streams or lakes in low-altitude mountainous regions. It can typically be seen perching on the tips of leaves or flying over the water

Courtship and mating

In order to secure mates from competition, males will rest on waterside plants and attempt to chase off any rival males that enter the area.^[4] When courting a female, the male will display its wings and tail-end clasper. After mating, the male will guard the female while she lays her eggs and continue to make courtship displays with his wings.

Females typically lay their eggs on the underside of aquatic plants.
