Litoria ewingii
Family: Hylidae
Common name: Brown Tree Frog
Description: This frog is pale cream brown above, with a broad brown band that runs down the back - starting between the eyes. Darker flecks are also scattered across the back. A black stripe runs from the snout, through the eye and tympanum (tight membrane covering the entrance to the ear), fading down the sides of the body. Below this dark stripe there is a pale stripe that runs from below the eye to the base of the arm. The groin and the backs of the thighs are yellow to red-orange. The belly is white, cream or yellow and granular. The skin on the back is smooth with low tubercles (lumps). Finger and toe pads are small, and the toes are half webbed. Occasionally green individuals of this species are found in western Victoria and South Australia.
Size: 45 mm
Habitat: This frog lives in many habitats including coastal lagoons and swamps, wet and dry sclerophyll forests, grasslands and bogs.
Call: A rapid "weep..eep..eep..eep" sound repeated 5 - 15 times.Call available in 
Windows Media or 
Quicktime audio. Recording Copyright © Murray Littlejohn.
Breeding: Males call throughout the year after rain, but breeding peaks in early spring and autumn.
Eggs: Are small and laid in clusters attached to twigs and stems, under the water.
Tadpoles: Are medium sized and range in colour from almost black to clear honey yellow. These tadpoles are fast swimmers and dart away when disturbed.
Similar species: This frog can be distinguished from Litoria paraewingi by its faster call and distribution.
Conservation Information
Suspected threatening processes
- Habitat modification (e.g. vegetation clearing, invasive weeds)
Population size: An estimate of the total number of adults present in the species entire range is >50000 individuals. Some factors affecting population size and distribution are known, but 1 or more major factors are unknown.
Population trend in Australia over the past 50 years: Population size stable or suspected to be stable or increasing.
Knowledge of population trend in Australia: Not currently monitored.
Population concentration: Not known to concentrate or exist in discrete locations. (e.g. the number of sites in which individuals group together either seasonally, such as breeding sites, or they may occupy discrete habitat patches within the broader landscape, such as discrete water bodies or drainage units.)
Ongoing management activities in Australia: None directed primarily at the taxon.
Reproductive potential for recovery: The average number of eggs deposited per adult female per year is 201-1000 eggs/female/year. Minimum age at which females are known or suspected to first reproduce is <2 years.
Range size in Australia: The size of the geographic area over which the taxon is distributed: > 1,000,000 km².
Distribution trend: Area occupied is stable or has increased. (This is an estimate of change in the portion of the total range that is occupied or utilised; it may not equal the change in total range.)
Knowledge of distribution in Australia: Broad range limits or habitat associations are known, but local occurrence cannot be predicted accurately.
