About Dendropsophus nanus (Boulenger, 1889)
Dendropsophus nanus, commonly called the dwarf treefrog, is a species of frog in the Hylidae family. Its known distribution includes northern Argentina, Paraguay, Uruguay, eastern Bolivia, Brazil, French Guiana, and Suriname. It is a very common species that occurs across a wide variety of habitat types and adapts well to anthropogenic disturbance. It typically lives in herbaceous vegetation along the edges of standing water. Breeding for this species occurs in temporary water bodies. A study of populations in Argentina found that the diet of Dendropsophus nanus consists mostly of dipterans and spiders. During cold seasonal periods, these frogs rely partially on stored fat reserves; they rely on these reserves to a greater degree than the sympatric species Hypsiboas pulchellus.
