The Spiny Leaf Insect is not a true Leaf Insect, but a species of Stick Insect. It is variable in colour and can be green, light brown or reddish brown. It is covered in sharp spines and the legs have flattened leaf-like projections. The head has an odd pointed cone shape and looks like it is on back to front. Males have much slimmer bodies, and two pairs of fully developed wings and can fly. Females have stout abdomens, a single pair of tiny wings and cannot fly. They rely on camouflage to avoid predators, looking like a stick with leaves. When disturbed they can strike out with their spiny legs. They often curl the end of their abdomen over their back like a scorpion. The Spiny Leaf Insect is a popular insect pet.
