Litoria littlejohni
Family: Hylidae
Common names: Littlejohn's Frog; Littlejohn's Tree Frog
Description: This frog is light brown on its back with darker flecks and spots. There is a faint dark broad band running down the back. A dark stripe runs from the snout, through the eye and tympanum (tight membrane covering the entrance to the ear), to the base of the arm. The groin, backs of the thighs and armpits are all red-orange. The belly is cream or yellow and granular. The skin on the back is warty. The finger and toes pads are large and the toes are two-thirds webbed.
Size: 55 - 60 mm
Habitat: This frog lives in sclerophyll forests, woodlands and heaths.
Call: A series of 6 - 14 drawn out "creeep-creeeep-creeeeeep".Call available in 
Windows Media or 
Quicktime audio. Recording Copyright © David Stewart.
Breeding: Males call during late winter and spring and this is when most of the breeding occurs.
Eggs: Are large and laid in clusters of up to 60 eggs. These clusters are attached to twigs, stems and branches in pools and streams.
Tadpoles: Are large and black or very dark grey. These tadpoles have been observed swimming in schools and eating eggs of Litoria verreauxii and their own species.
Similar species: This frog can be distinguished from Litoria jervisiensis by its call and its lack of a white stripe beneath the eye.
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 10001-50000 individuals, or size is unknown but suspected to be large. Factors affecting population size and distribution are unknown or unsubstantiated.
Population trend in Australia over the past 50 years: Population trend unknown; no information on habitat changes.
Knowledge of population trend in Australia: Monitored locally.
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: Management mostly related to enforcement of conservation laws.
Reproductive potential for recovery: The average number of eggs deposited per adult female per year is Minimum age at which females are known or suspected to first reproduce is 2-3 years.
Range size in Australia: The size of the geographic area over which the taxon is distributed:
Distribution trend: Decline, if any, unknown. (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.
