The red-eyed tree frog is a small, vibrantly coloured tropical frog. Its scientific name is, “Agalychnis callidryas”, comes from the Greek words kalos (meaning “beautiful”) and dryas (a “tree” or “wood nymph”).

Distribution and habitat

Red eyed tree frogs are known for their vibrant colors and distinctive appearance. They have bright green bodies with blue and yellow stripes, large bulging red eyes, and orange feet with sticky pads that help them cling to leaves and branches. These unique frogs prefer to live in areas near rivers and ponds in rainforests, where they can easily find water and a diverse range of insects to eat. They are commonly found in the humid lowlands of many Central American countries from Mexico to Columbia. Despite being high up in the trees, these frogs are not difficult to spot due to their striking coloration and loud vocalizations at night.


Phyllomedusine tree frogs are arboreal, meaning they spend a majority of their lives in trees; they are excellent jumpers. Despite their bright colouring, red-eyed tree frogs are actually not poisonous, and rely on camouflage to protect themselves. They are nocturnal, sleeping for most of the day.


Adult red-eyed tree frogs are primarily carnivores, eating crickets, moths, grasshoppers, flies, and other insects. Sometimes, they eat smaller amphibians. Tadpoles eat plants, algae, plankton, bacteria, and carrion.
