Breeding Biology

Eggs are laid in clusters that float on the surface of the water in flooded ditches and small temporary ponds. Tadpoles can reach a total length of up to nearly 7 cm, and are dusky brown in colour. They swim throughout all levels of water bodies, and take at least one month to develop into frogs, although tadpoles in colder areas may take much longer. Breeds during spring and summer.
