FLETCHER'S FROG Lechriodus fletcheri (Boulenger, 1890)
This moderately built frog attains 5cm in length. Common in rainforest areas along the NSW and SE Queensland coast, it may also occur near Cairns, Nth Queensland.
This frog occurs alongside the Great Barred Frogs (genus Mixophyes) with which it is commonly mistaken for being immature specimens.
Fletcher's Frog does not live in areas heavily disturbed by man adjacent to its habitat. It feeds on insects, and other small animals, with its' tadpoles being notoriously cannibalistic. The call is a 'g-a-r-u-p' lasting about a second, repeated every few seconds.
Fletcher's Frog is a summer breeder in small creeks and ponds within rainforest.

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.
