Pseudophilautus popularis, the common shrub frog, is a species of frogs in the family Rhacophoridae. It is endemic to Sri Lanka. Its natural habitats are subtropical or tropical moist lowland forests, arable land, pastureland, rural gardens, and heavily degraded former forest. Scientists have seen it between 0 and 1067 meters above sea level.
The adult male frog measures about 17.7 – 21.3 mm in snout-vent length and the adult female frog about 23.0 – 25.6 mm when full of eggs. The top of the frog's head and the skin of the dorsum are brown in color. The flanks are dark brown or black in color with some white or light blue marks. The inguinal area is gray-brown in color. The area around the tympanum has blue dots. The legs are brown with darker brown bars. The ventrum is gray-brown in color. The bottoms of the hind legs are yellow in color. The webbed skin is yellow in color.
This frog is classified as vulnerable. Scientists attribute this to habitat loss from urbanization and to pollution, fertilizers, and pesticides. Scientists note that one of the places where the frog has been found, Bellanwila-Attidiya sanctuary, is a protected area.

Possible
About 30% of wildlife watchers report a Common Shrub Frog sighting in Sinharaja Forest Reserve on a given day, based on 36 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 7th most-seen of the 25 amphibians we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
August
In that month about 40% of wildlife watchers report a Common Shrub Frog in Sinharaja Forest Reserve on a given day, against under 5% in July, the lowest month.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Common Shrub Frog sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Sinharaja Forest Reserve, in our data
Sinharaja Forest Reserve is the only park on Wallace's Line with enough records to rate Common Shrub Frog sightings: about 30% of wildlife watchers there report one on a given day.
Same genus: Pseudophilautus
The closest relatives of the Common Shrub Frog that you can see in Sinharaja Forest Reserve (genus Pseudophilautus, Shrub Frogs) are Sharp-snouted Shrub Frog (about 30%), Schneider's shrub frog (about 30%) and Hollow-snouted Shrub Frog (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Shrub Frog is recorded against all the amphibians logged in Sinharaja Forest Reserve (36 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.
