Immature stages have been collected from a wide variety of habitats in heavy or partial shade or in full sun: stream margins, marshes, marshy depressions, flood pools, ruts, lake margins, and rice field ditches. The water was turbid or colored, always fresh, stagnant or with a slow current. The sites were permanent, semipermanent, or temporary, without aquatic vegetation or with scarce or abundant aquatic grasses, submerged, and floating (Pistia) vegetation and green algae.
