Dendropsophus nanus, commonly called the dwarf treefrog, is a species of frog in the Hylidae family.

Distribution Range

Its known distribution includes northern Argentina, Paraguay, Uruguay, eastern Bolivia, Brazil, French Guiana, and Suriname.

Population Status and Disturbance Tolerance

It is a very common species that occurs across a wide variety of habitat types and adapts well to anthropogenic disturbance.

Habitat Microenvironment

It typically lives in herbaceous vegetation along the edges of standing water.

Breeding Location

Breeding for this species occurs in temporary water bodies.

Diet Composition

A study of populations in Argentina found that the diet of Dendropsophus nanus consists mostly of dipterans and spiders.
