Green tree frog

Litoria caerulea


Large variety of wetland habitats including urban areas, dry forest, woodland and grasslands close to streams and swamps. Preferring cool damp places.

Natural behavior

Nocturnal; mostly arboreal but will descend to water bodies during the breeding season


Plump with short robust limbs and smooth green skin, which can change shade slightly. Often having random, irregular white spots on back with a creamy white underbelly and toe discs present on tips of toes


Northern and Eastern Australia


Primarily an insectivore; eating spiders, crickets, cockroaches, grasshoppers, moths, lizards and other frogs. During the tadpole stage, diet is omnivorous eating algae, mosquito larvae and drowned insects


Breeding occurs in the wet season from November – February. Males can be heard calling during this time. Mating occurs in water where eggs are laid and fertilised in a jelly mass on the surface, which sink to the bottom before hatching. Eggs develop into tadpoles, then frogs, through a process called metamorphosis lasting around 6 weeks. Legs finally emerge and tails are re-absorbed

Social structure

Solitary; coming together during mating time only although they may congregate in favorable environments


Habitat loss with urban expansion, habitat destruction from pollution. International pet trade. Many Australian frog species are also affected by the Chytrid fungus, which results in death.
