Habitat and Ecology
It is associated with swamps, lakes and streams in the Central African forest belt, and it is often seen along large rivers. It can be found in undisturbed forest, but it has also been observed in very open bush land with no forest in the vicinity. The eggs are laid on leaves above still or flowing water, into which the larvae fall and develop.
It is a common species.
It is a very adaptable species, and is unlikely to be facing any significant threat.
It probably occurs in several protected areas.
Red List Status
Least Concern (LC)
