People have observed this frog on the leaf litter in primary and secondary rainforest. Scientists have seen this frog between 500 and 800 metres (1,640 and 2,620 ft) above sea level. Scientists found this frog in one protected park, Parque Estadual da Serra do Mar.

The male frogs go to temporary pools of water and call to the female frogs. The female frogs deposit eggs, 5-13 per clutch on rocks above the pools. The tadpoles hatch and go into the water. The tadpoles can be 25.8 mm (1.02 in) long, including the tail.
