Usually found near vegetation in swamps, ponds, backwaters, pools of small to large rivers (Ref. 5723, 10294) and oxbow lakes. Adults feed on microcrustaceans (chydorid cladocerans, cyclopoid copepods, ostracods), rotifers, unicellular algae (desmids and diatoms), and small dipteran larvae (Ref. 10294). Migratory behaviour is undetermined (Ref. 126106).
