Distribution: This species of frog is broadly spread, being found in Southeastern and Southern Brazil and all the way to Southeastern Paraguay and Northeastern Argentina. In Brazil, it is distributed from lowland to mountainous regions, occurring in the Atlantic Forest and Savanna. It is a species that adapts well and easily to changed regions, and may be expanding its geographical distribution due to human actions.

Habitat: Formations open to forests and in the edges riparian and gallery forests.

Habits: Crepuscular, nocturnal, and arboreal. They build their mud nests on the shores of lakes and rivers and can commonly be found on the trees. Males are territorial, and when in large population densities they exhibit parental care.

Diet: Insects and small arthropods.

Breeding: Oviparous, reproducing during the rainy season. This species may vocalize on vegetation or in shallow waters, although often within the small circles they build, serving as nests for spawning, and are located in forest or open areas on the banks of permanent or temporary ponds and streams. Females lay 3000-4000 eggs, which float on the water inside the nest. Outside the breeding season they may be found on the trees.

UFRA: Species spotted only in Wetlands with Herbaceous Plants.
