Peron’s Tree Frog (Litoria peronii): is also known as the Emerald Spotted Tree Frog, Laughing Tree Frog and Maniacal Cackle Frog. The last two names refer to its distinctive call. We will stick to Peron’s Tree Frog because it would seem to be the commonest common name.
Peron’s Tree Frog is between 45 to 75 millimetres long. This makes this species one of Australia’s largest native frogs. This does not include the introduced and obnoxious Cane Toad.
Peron’s Tree Frogs usually have bright yellow and black mottling on their groins, backs of thighs and armpits. They may have indistinct emerald green flecks on the back.
Peron’s Tree Frog is a species that comes in a variety of skin colours from very dark to light shades. They all have one distinctive feature. Their eyes have crossed-shaped pupils (see image).
Peron’s Tree Frog is found in the eastern parts of Queensland, New South Wales and Victoria as well as areas of South Australia.
They occupy a variety of habitats including wet and dry forests, woodlands, shrub lands and open areas. They are often found some distance from water and are very agile climbers.
Peron’s Tree Frogs are very common around Yallaroo. They inhabit our propagating structure and we have found them in one of water tanks. This has necessitated a vertical climb of at least three metres. A relative had a specimen living in her letter box for a number of weeks.
We have no trouble identifying this large frog because of its cross-shaped pupils.
Litoria peronii is a member of the large Hylidae family usually known as Tree Frogs. Some members of the family, including Peron's Tree Frog, have a large finger and toe pads. This enables these frogs to become efficient climbers. 
There is a very interesting web site that describes Australian frogs. This link will take you to the Peron’s Tree Frog section: http://frogs.org.au/frogs/species/Litoria/peroni/    The various images, on this site, will demonstrate the wide range of skin colour.
