Description

A small species of frog reaching up to 3 cm in body length. It has a green or brown back, sometimes with small brown patches, and a wide bronze stripe from the tip of the snout to near the groin if the back is green. There is a white stripe that follows underneath the bronze stripe, but passes under the eye instead of through it. The belly is white. The groin and thighs have an orange patch. The pupil is horizontal and the iris is gold. Fingers are slightly webbed and toes are about three-quarters webbed, both with small discs.

Breeding Biology

Eggs are laid as many small clusters that are attached to vegetation near the surface of the water in permanent or temporary ponds, lagoons, and swamps. Tadpoles can reach a total length of 4 cm, and have a translucent yellow-gold back. If viewed from the side, the lower half of the body will be white or silver, clearly separated from the colour of the back. Tadpoles often remain near the surface of the water, and take two and a half months to develop into frogs. Breeds during summer rains.

Similar Species

Looks similar to Litoria fallax and Litoria microbelos in its distribution, but has a different back colour pattern to Litoria microbelos. It can most easily be distinguished from Litoria fallax by its different call.
