BLUE MOUNTAINS TREE FROG Litoria citropa (Dumeril and Bibron, 1841)
This nicely coloured frog reaches 6 cm, and is found along the coast and ranges of south-east NSW and Victoria.
This frog is rarely found in large population densities. It is usually located in rock crevices, or under rocks near small permanent and semi-permanent creeks.
Occasionally adult specimens are found considerable distances from any possible breeding sites, usually in winter.
The Blue Mountains Tree Frog breeds in early spring. The call is a sharp scream followed by a trill.
The above was from the book Australian Reptiles and Frogs by Raymond Hoser and now available on a fantastic CD-Rom along with a vast amount of other information, papers and the like on reptiles, frogs and other wildlife.
