Habitat and Ecology
It occurs only in seasonally flooded grasslands, and breeds in both temporary and permanent pools.
It is a rare species and, due to ongoing declines in the quality and extent of its habitat, the population is suspected to be decreasing.
The transformation of the original grassland habitat into agricultural land, and the subsequent pollution from pesticides are major threats to this species. Urbanization is also a threat.
This species was previously included in the genus Pternohyla which was synonymized with Smilisca (Faivovich et al. 2005).
