Leaf insects eat blackberry brambles and rose, oak and evergreen oak leaves. Leaf insects are herbivorous, which means that they consume only plant material.

Originating from South and Southeast Asia through Australia, leaf insects eat leaves and consume water that gathers on the leaves. Because of their simple diet, leaf insects are considered easy pets for children.

Leaf insects are masters of camouflage, as they mimic the leaves that they feed on to provide themselves with extra protection from predators. They are flat, and colored green and brown, with leaf-like veins. They move with the wind to blend in with the leaves, and tend to be more active at night.

Young leaf insects are capable of regenerating any lost limbs through the process of molting. Leaf insects have hindwings, though the females are flightless.
