Uperodon systoma is a species of narrow-mouthed frog found in Pakistan, India, Nepal, and Sri Lanka. It is known under many different common names: indistinct frog, marbled balloon frog, and lesser balloon frog. As the common names suggest, Uperodon systoma have a very stout appearance with a relatively small head. They grow up to 64 mm (2.5 in) in snout–vent length.
Uperodon systoma lack teeth. This unusual feature is probably related to their diet that (after metamorphosis) consists mainly of termites and ants, with other insects appearing in smaller numbers. It is suggested that in capturing such small but spatially clustered prey items teeth would not be very useful; instead, the prey are gathered using their tongue.
Uperodon systoma is a fossorial species that buries itself in soil. These frogs have been observed in a number of habitats, such as dry forests, plains, gardens, and agricultural areas. Adults are only seen during the summer monsoons; otherwise they retreat into the soil. Feeding may be concentrated to rainy nights during the monsoon when termites emerge to swarm.

With luck
About 10% of wildlife watchers report a Marbled balloon frog sighting in New Delhi on a given day, based on 11 verified sightings from GBIF citizen-science data. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
July and August
In those months about 20% of wildlife watchers report a Marbled balloon frog in New Delhi on a given day, against under 5% in September to April, the lowest months. Those are among New Delhi's wettest months, with about 210 mm of rain a month against almost none in November.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Marbled balloon frog sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
2nd of 2
Of the 2 cities where we can rate Marbled balloon frog sightings, New Delhi ranks 2nd at about 10%. The best odds are in Lucknow (India, about 30%).
Same order: Anura
The closest relatives of the Marbled balloon frog that you can see in New Delhi (order Anura, Frogs and Toads) are Common Indian Toad (about 10%), Indus Valley Bullfrog (about 10%) and Common skittering frog (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Marbled balloon frog is recorded against all the amphibians logged in New Delhi (11 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.
