By looking at differences in its appearance, call and DNA, we now know that they are distinct species, bringing the number of known frog species in Australia to 239. The Cape York Graceful Treefrog (Litoria bella) was initially mistaken as the Graceful Treefrog (Litoria gracilenta). kookaburra, butcher bird, magpie), bats, goannas, rats, other frogs, cane toads, fish and domestic pets. Adult frogs are eaten by snakes, birds (e.g. Tadpoles are eaten by pond fish, birds, water spiders, and water bugs (e.g. What eats me: Frogspawn is eaten by ants, fish, small lizards and birds.

After mating, the female lays the eggs in a clump of jelly attached to vegetation. However, during rain or in areas of forest that are shaded and moist, these frogs can be found sitting on leaves near water hunting.ĭuring the Spring and Summer, the males call to the females with a long drawn out “waaaaaa” that sometimes sounds like a growl. During the hotter parts of the day they retreat into protected shady foliage to avoid the sun and potential predators. Graceful Treefrogs can be found in open forests, woodlands and suburban gardens hiding in vegetation around water. This 45mm frog has predominantly green skin, with lemon yellow flanks, belly, upper arms and feet and a yellow “eyebrow” that sits above and behind bright orange eyes. Thanks to FrogID, a national citizen science project, and thousands of people recording the calls of frogs across Sydney, we finally have enough data for the first compelling evidence of the disappearance of the Green Tree Frog from most of Sydney.The Graceful Treefrog (Litoria gracilenta), also known as the Dainty Treefrog, can be found along the coast from Cape York in Northern Queensland to Sydney. Several scientific reports have noted the apparent decline of the Green Tree Frog in Sydney, however there has been no real evidence of this decline - until now. So, it’s not surprising that people noticed something was amiss. It is also rather bold, often moving in with us humans (there’s a reason its affectionately called the Dunny Frog), and males have a distinctive call that can be heard from far away. The Green Tree Frog is large and easily recognizable. 21).įor decades, there have been murmurings amongst frog biologists and nature-lovers across Sydney that the Green Tree Frog is no longer as common as it once was. In 1922, Launcelot Harrison noted that the species was “very generally distributed both in gardens and in the bushland surrounding them” in Mosman, with “perhaps a hundred frogs” observed on a night (Harrison 1922, p. It was reported from many central Sydney suburbs, including Sans Souci, Botany Bay, Randwick, Waverley, Bondi, Mosman and Curl Curl.
