The Montevideo tree frog (Boana pulchella) is a species of frog in the family Hylidae found in eastern, central, and northern Argentina, south-eastern Brazil, south-eastern Paraguay, and Uruguay. It is a common species occurring in open habitats in forests, grasslands, and flooded savannas. Breeding takes place in permanent ponds and flooded grasslands.
The diet of Argentinean Boana pulchella was found to consist mostly of spiders, dipterans and, crickets. During the cold time of the year, these frogs continue to feed at high rate, instead of partly relying on their fat reserves as the sympatric Dendropsophus nanus do. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Montevideo Tree Frog is recorded against all the amphibians logged in Buenos Aires (203 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.
