Litoria ewingii are generally an overall light brown colour, although this may very from a white/grey to a dark brown background. They all have a white stripe along the jawline from the axilla, to at least, below the eye and sometimes to the end of the snout. Most frogs have a lighter patch on the top of the head, extending from between the eyes to the tip of the snout. The belly and throat are usually white or cream and the undersides of the thighs are bright orange. The eardrum (tympanum) is quite distinct and easily visible. The fingers and toes have slightly expanded tips (suckers) that are used for climbing, and webbing is usually absent. These are generally quite small frogs ranging from about 30-50 mm long (SVL).

Range and population.
From the south-eastern corner of South Australia, east along the south coast of Victoria and into far south-eastern New South Wales. Isolated populations occur along the coast and ranges of central New South Wales. Widely distributed in Tasmania.The extent of occurrence of the species is approximately 311900 km2Widespread and common.
In New Zealand it has now become quite widespread over all of the South Island and most of the southern and central North Island, with the odd record in the northern areas.

The most notable mammal present is the endemic Kangaroo Island Kangaroo (Macropus fuliginosus fuliginosus), the icon for whom the island was named upon European discovery in 1802. A smaller marsupial present on the island is the Tammar Wallaby (Macropus eugenii). An endemic dasyurid is the Critically Endangered Kangaroo Island Dunnart (Sminthopsis aitkeni), which is found only in the west of the island in Eucalyptus remota/E. cosmophylla open low mallee, E. baxteri low woodland or E. baxteri/E. remota low open woodland. The Common Brush-tailed Possum (Trichosurus vulpecula) is a widespread folivore native to Australia.

Monotremes are also represented on the island. There is also an introduced population of the Duck-billed Platypus (Ornithorhynchus anatinus) in the western part of the island in Flinders Chase National Park. The Short-beaked Echidna (Tachyglossus aculeatus) is also found moderately widespread on Kangaroo Island.

Chiroptera species on Kangaroo Island include the Yellow-bellied Pouched Bat (Saccolaimus flaviventris), which species is rather widespread in Australia and also occurs in Papua New Guinea. Australia's largest molossid, the White-striped Free-tail Bat (Tadarida australis) is found on Kangaroo Island. Another bat found on the island is the Southern Forest Bat (Eptesicus regulus), a species endemic to southern Australia (including Tasmania).

Several anuran species are found on Kangaroo island: Brown Tree Frog (Litoria ewingii), Spotted Marsh Frog (Limnodynastes tasmaniensis), Painted Spadefoot Frog (Neobatrachus pictus), Brown Toadlet (Pseudophryne bibroni) and Brown Froglet (Crinia signifera).

The Heath Monitor (Varanus rosenbergi ) is a lizard that grows up to a metre in length, preying on smaller reptiles, juvenile birds and eggs; it is frequently observed on warmer days basking in the sunlight or scavenging on roadkill. The Black Tiger Snake (Notechis ater) is found on Kangaroo Island. Another reptile particularly associated with this locale is the Kangaroo Island Copperhead (Austrelaps labialis).

The Glossy Black Cockatoo (Calyptorhynchus lathami) is found on the island, especially in the western part, where its preferred food, fruit of the Drooping Sheoak, is abundant. The Kangaroo Island Emu (Dromaius baudinianus) became extinct during the 1820s from over-hunting and habitat destruction due to burning.

Marine mammals that are observed on the island include the Australian Sea Lion (Neophoca cinerea) and New Zealand Fur Seal (Arctocephalus forsteri), each species of which is native to Kangaroo Island, and abundant at Admiral's Arch as well as at Seal Bay.

Kangaroo Island is not so adversely impacted by alien species grazers as parts of the mainland. No rabbit species are present on the island, and introduced (but escaped) Domestic Goats (Capra hircus) and pigs (Sus scrofa) have generated only minor issues. However, a Koala (Phascolarctos cinereus) population introduced to the island in the 1920s has caused significant damage to certain woodland communities, especially to Manna Gum trees.

Various habitats from alpine to semi-arid shrubland, but most common in flooded grassland or marshes. Can also be found in suburban gardens. Common in both temporary and permanent water.

Breeding occurs at any time of year with peaks in spring and autumn. Males call from the ground or in low vegetation at the water's edge or in water on floating vegetation. About 500 - 700 eggs are laid in small clumps attached to submerged vegetation. In still water in ponds, dams, lakes, streamside ponds and flooded roadside ditches. Metamorphosis takes 6-7 months.

Threats: Water pollution where the species occurs in urban areas.

This species is a popular species with children and many tadpoles are raised to the froglet stage. Much of its distribution in New Zealand can be correlated with deliberate releases by humans of the newly metamorphosed froglets.
