General Information

The Cricket Coqui is one of only two arboreal (tree dwelling), mountain Coqui species; the other is E.hedricki.


A tiny frog, 5/8 inch (16 millimeters) long, E. gryllus is yellowish or greenish-brown, with limbs of a lighter shade than the body. The throat can be light green and the abdomen white or greenish-white, occasionally with a blue or gold iridescence. It has a triangular snout with a pointed tip.


Cricket Coquis are insectivorous, eating small insects such as flies and mosquitoes. An arboreal (tree dwelling) frog, during the daytime this animal usually hides in epiphytic (growing on another plant) bromeliad plants on the trunks of trees to conserve moisture. At night E. gryllus calls from tree branches and leaves at considerable heights above the ground. The voice is a cricket-like sound for which it is named.


The Cricket Coqui occurs at the edges of openings in mountainous forest areas above 500 feet (150 meters) in elevation.

Where to look for this animal in the EYNF
