Orange-Thighed Frog, Litoria xanthomera

The Orange-Thighed Frog (Litoria xanthomera) is a tree frog that is native to a small area of tropical Queensland, Australia. It is a green frog with distinctly orange colored eyes, and is much like the Red-Eyed Tree Frog (Litoria chloris) in appearance.

Reaching a length of about 5.5 centimeters, this frog is of medium size. It is slender, with a thin body, flat head, and large eyes, which are orange. The dorsal surface is green, with bright yellow feet and vocal sac, and a yellow band down its flank. The inner surfaces of the legs are yellow also, and the outer surfaces of green. It is distinguished, physically, from the Red-Eyed Tree Frog by the presence of bright orange thighs.

The male frogs gather around still ponds, and emit their call from low branches, or from the edges of the water. The call is a long “aaa-rk”, followed by a soft trill. They give their call after heavy monsoon rains. The males call in a large chorus; amplexus takes place where the frog calls, and the male and the female frog move to the laying site.

The eggs are brown, and are in a mass consisting of about 800 to 1,600 eggs. the tadpoles are identical in appearance to those of the Red-Eyed Tree Frog.
