At night, this semi aquatic frog congregates at permanent or semi-permanent ponds in open areas. The males call from floating vegetation or emergent grasses (Rodríguez and Duellman, 1994). This species breeds in the wetlands with which it is associated. It has been recorded from flooded roadside ditches (Trinidad).
