Habitat and ecology

The frog can be found in wetland areas of Mauritius and is known to live in agricultural fields, secondary vegetation and marshy areas as well as rainforest, dry forests, savannas and grasslands in other parts of its range. It is believed to have a preference for moist grassy areas near wetlands or watercourses.  P. mascareniensis preys on insects and is active both day and night. Similar to other frogs and toads, males call loudly to attract females. Mating is followed by the depositing of large bubbly egg masses in ponds, puddles or wetlands.
