Montevideo tree frog

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.
