Pseudophilautus viridis, or the dull-green shrub frog, is a species of frogs in the family Rhacophoridae. It is endemic to Sri Lanka and occurs in the central hills of south-central Sri Lanka. Adult males measure 27.6–31.5 mm (1.09–1.24 in) and females 27.4–36.3 mm (1.08–1.43 in) in snout–vent length. Males usually have horn-like spinules in the dorsum; females are shagreened. The tympanum is not prominent whereas the supratympanic fold is distinct. The canthal edges are indistinct. The fingers are without webbing whereas the toes are medially webbed. The upper parts are light green, except for the upper edge of supratympanic fold and outer edge of upper eyelid that are yellow; some individuals are brown. The flanks are light yellow with light-blue patches. The upper lip is light yellowish-green and the lower one is white. Underparts are flesh coloured.
Pseudophilautus viridis is a habitat generalist that occurs in both open and closed-canopy vegetation, including cloud forests and adjacent man-made habitats, at elevations of 1,555–1,830 m (5,102–6,004 ft) above sea level. They are arboreal, found some 1 to 5 m (3 to 16 ft) above the... Wikipedia →

Possible
About 20% of wildlife watchers report a Dull-green Shrub Frog sighting in Horton Plains National Park on a given day, based on 25 verified sightings from GBIF citizen-science data from 2019 to 2026. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
May
In that month about 40% of wildlife watchers report a Dull-green Shrub Frog in Horton Plains National Park on a given day, against under 5% in September to November, the lowest months. That is one of Horton Plains National Park's wettest months, with about 270 mm of rain against 80 mm in March.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Dull-green Shrub Frog sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Horton Plains National Park, in our data
Horton Plains National Park is the only park on Wallace's Line with enough records to rate Dull-green Shrub Frog sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Dull-green Shrub Frog is recorded against all the amphibians logged in Horton Plains National Park (25 verified sightings from 2019 to 2026), 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.
