What do glass frogs eat?

The feeding behavior of glass frogs is not well studied, but they appear to primarily eat small insects and arthropods. Glass frogs have been observed hunting insects in the dense vegetation beside tropical rivers. In captivity, glass frogs are fed fruit flies.

Glass frogs live in the trees of humid South American forests. Most species are very small and measure about 1 inch in length. They hunt primarily on the forest floor and in tall vegetation. Traits such as their favorite prey and whether or not they hunt in trees are unknown. The frogs have excellent vision and voracious appetites, and they have been observed leaping at prey mouth-first.
