Euphlyctis hexadactylus, also known as the green pond frog, Indian green frog, and Indian five-fingered frog, is a common species of aquatic frog found in Pakistan, India, Bangladesh, and Sri Lanka. The nominal taxon likely represents a species complex.
The following description is from Boulenger: Vomerine teeth in two oblique series extending beyond the hinder edge of the choanae. Head moderate; snout rather pointed; cauthus rostralis indistinct; intororbital space much narrower than the upper eyelid; tympanum distinct, as large as the eye. Fingers slender, acutely pointed, first extending a little beyond second; toes webbed to the tips, which are acutely pointed; outer toe strongly fringed; fourth toe not very much longer than third or fifth; subarticular tubercles of fingers and toes very small; inner metatarsal tubercle small, conical; no outer tubercle. When the hind limb is corned forwards along the body, the tibio-tarsal articulation reaches the eye. Skin smooth, with more or less distinct rows of pores round the neck, sides, and belly. Brown above; sometimes a light vertebral line: two blackish streaks on the hinder side of the thighs, sometimes indistinct... Wikipedia →

Possible
About 30% of wildlife watchers report an Indian Five-Fingered Frog sighting in Dhaka on a given day, based on 19 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
September
In that month about 80% of wildlife watchers report an Indian Five-Fingered Frog in Dhaka on a given day, against under 5% in February–April, June–July and November–December, the lowest months. That is one of Dhaka's wettest months, with about 280 mm of rain against 10 mm in January.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Indian Five-Fingered Frog 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.
Yes
Of the 3 cities where we can rate Indian Five-Fingered Frog sightings, Dhaka has the highest daily chance: about 30%. Next come Colombo [Sri Jayawardenepura Kotte] (Sri Lanka, about 30%) and Chennai (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Indian Five-Fingered Frog is recorded against all the amphibians logged in Dhaka (19 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.
