The natural habitats of Scinax rostratus are sub-humid scrubby forests and moist savannas. It can be found from sea level to 1300m (4,300feet) above sea level. It is an arboreal species found perched on low vegetation at the edges of temporary or permanent ponds near moist forests. It breeds in temporary ponds. It tolerates some habitat modification. However, habitat loss is a threat to it. It occurs in a number of protected areas.
