The Yellow Treefrog (Dendropsophus microcephalus) is a common small hylid found from southern Mexico all the way down into northern South America and even on the Atlantic Coast of Brazil. Throughout their range, these cute little frogs are found in lowland tropical areas including flooded grasslands, pastures and other disturbed habitats.  It have found them in Mexico and Costa Rica calling from flooded roadside ditches.

They are generally pale yellowish with some brown markings on the back that may form a net-like pattern in some individuals.

Their call is an insect like "crick, crick" sound. When first heard, it seems rather "unfrog-like".  These Yellow Treefrogs were recorded in the grasslands east of Caño Negro, Costa Rica.
