Palenque, Chiapas, Mexico
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.
