The diet of the green tree frog consists mainly of insects such as moths, cockroaches, and locusts. They also eat spiders and can include smaller frogs and even small mammals (including bats) among their prey. Frog teeth are not suited to cutting up prey, so the food item must be small enough to fit inside its mouth. Many frogs flick out their sticky tongues at prey and the victim sticks to the tip and is drawn back into the mouth and consumed. A green tree frog uses this technique for smaller prey; for larger items, however, it pounces, then pushes the prey into its mouth with its hands.
