The Phasmatodea are an order of insects whose members are variously known as stick insects, stick-bugs, walkingsticks, stick animals, or bug sticks. They are also occasionally referred to as Devil's darning needles, although this name is shared by both dragonflies and crane flies. They can be generally referred to as phasmatodeans, phasmids, or ghost insects, with phasmids in the family Phylliidae called leaf insects, leaf-bugs, walking leaves, or bug leaves. The group's name is derived from the Ancient Greek φάσμα phasma, meaning an apparition or phantom, referring to their resemblance to vegetation while in fact being animals. Their natural camouflage makes them difficult for predators to detect; still, many species have one of several secondary lines of defense in the form of startle displays, spines or toxic secretions. Stick insects from the genera Phryganistria, Ctenomorpha, and Phobaeticus include the world's longest insects.

Megacrania batesii, commonly known as the peppermint stick insect, is an unusual species of stick insect found in northeastern Australia, the Bismarck Archipelago, the Solomon Islands, New Guinea, and possibly as far north as the Philippines. It is notable for its aposematic coloration, as well as its robust chemical defense mechanism. Its common name refers to the irritating fluid — with an odor resembling peppermint — that it sprays as a defensive action from a pair of glands located at its prothorax when threatened, as well as the cylindrical, twig-like shape of its body. A member of the subfamily Megacraniinae, it was first described by English naturalist and explorer Henry Walter Bates in 1865.

It was first described by George Robert Gray in 1832 and was the first phasmid he discovered. Leaf insects have extremely flattened, irregularly shaped bodies, wings, and legs. They are usually about 5–10 cm long. They are called leaf insects because their large, leathery forewings have veins that look similar to the veins on the particular type of leaves they inhabit. Its scientific name bioculatum means "two-eyed" and refers to the two dots located on the abdomen just in this species.
Eurycantha calcarata is a species of phasmid endemic to Australasia.
Acanthoxyla prasina, the prickly stick insect, is a stick insect in the order Phasmatodea and the family Phasmatidae.
