Distribution of the Dainty Green Tree Frog

Litoria gracilenta.

The Dainty Green Tree Frog or Graceful Treefrog (Litoria gracilenta) is a tree frog native to eastern Queensland, and north-eastern New South Wales, Australia. It ranges from northern Cape York in Queensland to Gosford in New South Wales, with a small and most likely introduced population in Hornsby Heights in Sydney. It is the faunal emblem of the City of Brisbane^[1]

Description

The Dainty Green Tree Frog is a slender, medium sized frog, reaching a length of 45 mm. It is a rich green on its dorsal surface, with a yellow ventral surface. It has a coarse, granular skin with bright orange eyes, some speciemens have a light blue ring following the circumference of the eye. The posterior of the thigh is purple-brown or maroon and the Tympanum is visible. In most specimens a thin yellow or white line runs from its nostril to its eye, and this distinguishes it from the closely related Red-eyed Tree Frog (Litoria chloris) and Orange-thighed Frog (Litoria xanothmera), which both lack this line. If this feature is lacking the granularity of the dorsal surface and size (L. gracilenta is smaller) will separate it from both Litoria chloris and Litoria xanothmera.

The fingers of L. gracilenta are three-quarters webbed, while the toes are fully webbed.^[2]

Ecology and behaviour

The Dainty Green Tree Frog is commonly found in vegetation emerging from the water in streams and swamps, often in temporary water. It is found in a range of habitats including rainforest, woodland and forest. It is commonly found near human developments, in gardens or farms. Due to its common occurrence on fruit and vegetable farms, particularly bananas, it is commonly transported around Australia with fruits or vegetables, frequently becoming a lost frog. This is common among many frog species, and is of concern due to the much faster rate at which it can spread disease.

This species is usually seen after heavy rain during spring and summer. It breeds in flooded grassland and small ponds.^[3] The males will call during summer after rain, and the call is a long "waa" or "wee". Others describe the call as a long "growl-like 'aarrrc' repeated frequently. Forms noisy choruses during summer breeding season."^[4] The eggs are laid in a clear jelly lump in water,^[5] and are attached to vegetation. Tadpole development takes approximately 14 weeks. The tadpoles are a dark brown colour, with a clear, yellow tinge on the body wall.

As a pet

It is kept as a pet^[6], in Australia this animal may be kept in captivity with the appropriate permit.
