Stoney Creek Frog
The Stoney Creek Frog (Litoria wilcoxi), is a ground dwelling tree frog of the family Hylidae. It is native to Eastern Australia. This species is found in woodland, rainforest and sclerophyll forest. It is normally associated with rocky flowing streams, however it will also inhabit dams in suitable forest.
Female Stoney Creek Frogs reach a maximum length of 2.75 inches. The males maximum length is 1.7 inches. It has reduced toe pads. Like most frogs, the color of the Stoney Creek Frog is variable. The dorsal and ventral surfaces range from gray to brown. A thin, black line runs from the snout to the eye, widens after the eye, and continues uninterrupted until the base of the arm. The posterior thighs will be black with yellow or green spots (sometimes hard to detect on a first glance basis).
During the mating season, the males congregate around streams/rivers and develop a brilliant lemon-yellow pigment on their skin, which can range from completely covering the body, to just covering the dorsal surface. The brightness of the yellow may vary between individuals.
The Stoney Creek Frog is unusual in relation to most of the Litoria genus because it lacks a vocal sack. The call is a series of soft trills, which can only be heard within a several feet of the frog. The frog will call near both moving and still water sources.
This species is almost identical physiologically to Lesueur’s Frog (Litoria lesueuri) and is identical physiologically to Litoria jungguy. It can be distinguished from Lesueur’s Frog by the presence of blue spots on the thigh, which are missing in the Stoney Creek Frog. Geographical distribution and genetic testing are the only methods of differentiating the Stoney Creek Frog and Litoria jungguy.
