Blue Mountains Tree Frog, Litoria citropa

The Blue Mountains Tree Frog (Litoria citropa) is a species of tree frog that is endemic to the coastal and highland areas of eastern Australia, from just south of Newcastle NSW, to eastern VIC. The Jenolan Caves Tree Frog, a population previously separated as L. jenolanensis, is nowadays included in this species.

This tree frog is of moderate size, up to about 60 millimeters long. Its dorsal surface is brown with a few darker colored flecks. There is a dark stripe that extends from the nostril, above the tympanum, to the groin. There is a lighter colored golden stripe above and adjacent to the dark stripe. The frog is usually green on the side of the head, the arms, legs, and side of the body. The amount of green on an individual frog can range from almost none at all to an all green color morph. The green coloration can occasionally be aqua-green. The armpit, thigh, groin, and the inner section of the foot are bright red-orange. The belly features the color white.

This species of tree frog is associated with flowing rocky streams in woodland and wet or dry sclerophyll forest. This species has a two-part call, the first is a strong “warrrrrk” followed by a number of shorter notes that sound like a gold ball going in a hole. The males call from the side of the stream in vegetation and rocks in the streams from spring to summer, most commonly after heavy rain.

If is often found in highland areas, particularly the Blue Mountains, hence its name. The species Litoria jenolanensis is suspected to be genetically the same as this species.

Tree frogs usually consume a variety of insects; in captivity, they consume gut-loaded crickets, their own tadpoles, guppies, spiders, and worms.
