The eastern dwarf tree frog (Drymomantis fallax), also known as the eastern sedge frog, is a species of tree frog native to Australia. It is a small and very common frog found on the eastern coast of Australia, from approximately Cairns, Queensland to Ulladulla, New South Wales. Individual frogs of this species are often found elsewhere, having been accidentally relocated by transported fruit or horticultural products. Two naturalised populations are known outside of its native range: a population successfully established on Guam around 1968, and breeding populations have established in multiple suburbs of Melbourne, Victoria.
The eastern dwarf tree frog is a small species of frog; females can reach a maximum size of 25–30 mm, while males may only reach 20 mm when fully grown. The dorsum is usually green in colour, but can range from brown to bright green, and occasionally has black flecks. The ventral surface is white with a granular texture. A distinct white line runs from under the eye to above the arm. A brown line begins from the nostril, continues across the eye, and can extend between the dorsal and ventral colours. This species' toe discs are only slightly... Wikipedia →

Rare
Under 5% of wildlife watchers report an Eastern Dwarf Treefrog sighting in Melbourne on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 7th most-seen of the 9 amphibians we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
December
In that month about 10% of wildlife watchers report an Eastern Dwarf Treefrog in Melbourne on a given day, against under 5% in January to November, the lowest months.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Eastern Dwarf Treefrog sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
3rd of 3
Of the 3 cities where we can rate Eastern Dwarf Treefrog sightings, Melbourne ranks 3rd at under 5%. The best odds are in Sydney (Australia, about 20%) and Brisbane (Australia, about 20%).
GBIF citizen-science records
It is estimated from how often the Eastern Dwarf Treefrog is recorded against all the amphibians logged in Melbourne (25 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
