Litoria bicolor és una espècie de granota que es troba al nord d'Austràlia.
The northern dwarf tree frog (Litoria bicolor) is a small species of tree frog native to northern Australia, from the Kimberly region of Western Australia to Bowen, Queensland, and Aru Islands of Indonesia.
These small frogs are also commonly called sedge frogs.
The population occurring in Indonesia may not be L. bicolor, and research on call structure or genetics is needed to confirm its taxonomic status.
The northern dwarf tree frog is small, slender tree frog growing up to 30 mm in length.
It has a green dorsal surface and a thin bronze dorsolateral band that begins at the eye.[1]
There is often a central bronze band running along the spine of the back. A narrow white stripe runs from under the eye, at the corner of the mouth, to the base of the arm. The ventral surface is cream or yellowish, with golden reflections on the thighs and groin area. The male throat is speckled with a darker color. The skin is granular in the belly and femoral region, but smooth elsewhere.
The iris of the eye is golden, the eardrum is distinct, the vomerine teeth are absent, and there is a strong pectoral fold. There are disks on the fingers and toes, the fingers are slightly webbed, and the fringed fingers are about three-quarters of a palm. There is an inner but not outer metatarsal tubercle, and the second finger is longer than the first.[2]
Most abundant in grassland or marshy areas, but also occurs along permanent or semi-permanent streams, billabongs and floodplains. Breeding starts with summer rains and 10-24 eggs are laid on submerged vegetation in temporary pools. Males call from around the breeding site from elevated positions. The call is a "wree-e-eck pippip" with the second part of the call starting before the first part finishes. Tadpole metamorphosis takes 70 to 80 days.
The northern dwarf tree frog is a member of the Litoria fallax complex, which includes also includes the eastern dwarf tree frog (L. fallax), Cooloola tree frog (L. cooloolensis) and Olongburra frog (L. olongburensis). All these species are similar in appearance (small, <30 mm and similar body shape) and have a similar call (ratchet-like "wreek"). The northern dwarf tree frog is most similar to the eastern dwarf tree frog. They occur together along the east coast of Queensland. L. bicolor can be distinguished from L. fallax most readily by the presence of a bronze stripe that runs down the flanks and the call. The first phase of the call of L. bicolor is twice as long as that of L. fallax.

Litoria bicolor es una especie de anfibio anuro de la familia Hylidae,[2][3]originaria de Australia y las islas Aru.[2][4]
Los adultos miden 3 cm de largo. Tienen un poco de membrana interdigital en sus patas delanteras y más en sus patas traseras.[5] Son verdes con una franja de bronce sobre cada ojo sobre sus cuerpos. Hay una franja blanca debajo de la franja bronce.[6] Las ranas más jóvenes son marrones, pero se tornan verdes cuando crecen.[4]
Viven en humedales con espesa vegetación, a veces cerca de los humanos.[4]
Ponen huevos en pequeños grupos unidos a las plantas justo debajo de la superficie del agua. Los renacuajos pueden crecer hasta 5 cm de largo y tomar dos meses y medio para comenzar a convertirse en ranas.[6][4]
Sus nombres comunes en inglés, "northern dwarf tree frog" y "sedge frog," significan, respectivamente, "rana de arboles pequeña del norte" y "rana de ciperáceas".[6]

Cette espèce est endémique d'Australie[1]. Elle se rencontre en Australie-Occidentale dans la région du Kimberley, dans le nord du Territoire du Nord et dans le Nord du Queensland le long des côtes jusqu'à Bowen.
Sa présence sur les îles Aru avait été rapportée[2] mais l'appartenance à cette espèce de des spécimens qui y avaient été collectés a été écartée[3].
Les mâles mesurent de 23 à 27 mm et les femelles de 25 à 29 mm[4].
