The New England tree frog or glandular frog (Litoria subglandulosa) is a species of frog in the Hylidae family, endemic to Australia. Its natural habitats are temperate forests, subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, temperate shrubland, rivers, and pastureland. It is threatened by habitat loss.[1]
Description
The male New England tree frog reaches a snout-to-vent length of 40 mm (1.6 in) while the females reach 50 mm (2.0 in). The upper parts are green or greenish-brown often flecked with black. A white line runs along the upper lip and a straw-coloured line runs from the snout, through the eyes and tympani to the groin. The lower parts of the sides and the back of the thighs are bright orange-red. There are enlarged pads on the digits enabling the frog to climb. This frog is very similar in appearance to the Blue Mountains tree frog (Litoria citropa) but as their ranges do not overlap, there is little chance of confusion.[2] The skin is smooth whereas in the closely related and similar-looking Davies' tree frog (Litoria daviesae) the skin usually has small raised bumps.[3]
Distribution
The New England tree frog is native to the New England Tableland in eastern Australia where it occurs at altitudes between 500 and 1,100 metres (1,600 and 3,600 ft). Its range extends northwards from the Werrikimbe National Park in New South Wales to southern Queensland and in the Nowendoc area it is the most common species of frog present in streams. It is an adaptable species and occurs in both wet and dry sclerophyll forests, in mountain woodland and cleared pasture. It is likely to be present in any stream with well-vegetated verges.[2]
Behaviour
Male frogs start calling at night in August or September and the breeding season continues until December, the call being described as a series of “orak..orak..orak” sounds continuing for about ten seconds. The males advertise their presence from logs or low vegetation beside streams, especially favouring Callicoma and Lomandra. The eggs are laid in shady parts of the stream and attached to submerged vegetation. The tadpoles grow to a length of about 35 mm (1.4 in) and are unique among Australian treefrog tadpoles in not having horny beaks, instead having a ring of tentacle-like papillae surrounding the mouth. It is not known on what the tadpoles feed but the adult frogs are presumed to eat small invertebrates. Their habits outside the breeding season are little known.[2]
