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.
Extatosoma tiaratum, commonly known as the spiny leaf insect, the giant prickly stick insect, Macleay's spectre, or the Australian walking stick, is a large species of Australian stick insect. The species has the Phasmid Study Group number PSG9.
Carausius morosus is a species of Phasmatodea (phasmid) often kept as pets by schools and individuals. Culture stocks originate from a collection from Tamil Nadu, India. Like the majority of the Phasmatodea, C. morosus are nocturnal. Culture stocks are parthenogenetic females that can reproduce without mating. There are no reports of males, although in captivity, gynandromorphs are sometimes reared.
Timema is a genus of relatively short-bodied, stout and wingless stick insects native to the far western United States, and the sole extant member of the family Timematidae. The genus was first described in 1895 by Samuel Hubbard Scudder, based on observations of the species Timema californicum.
Argosarchus is a monotypic genus in the family Phasmatidae containing the single species Argosarchus horridus, or the New Zealand bristly stick insect, a stick insect endemic to New Zealand. The name "horridus" means bristly in Latin, likely referring to its spiny thorax.

Acanthoxyla prasina, the prickly stick insect, is a stick insect in the order Phasmatodea and the family Phasmatidae. It is native throughout New Zealand, although it is less frequently reported than "common" stick insect species. It has been introduced to Britain, predominantly Cornwall and Devon, and to the south-west region of the Republic of Ireland. It has a thorny skin, which is used as camouflage.
Acanthoxyla inermis is an insect that was described by John Salmon in 1955. Acanthoxyla inermis is included in the genus Acanthoxyla, and family Phasmatidae. No subspecies are listed. This species is native to New Zealand but has been unintentionally moved to Great Britain where it has grown a stable population and is the longest insect observed, and the most common of the stick insects that have established themselves on the island.
Aretaon asperrimus is a species of insect in the Aretaon genus of the Phasmatodea order. The sometimes used common name thorny stick insect is a bit misleading, since the species does not correspond to the typical stick-like habitus and many other species are thorny as well.
Orestes mouhotii is an insect species belonging to the order of Phasmatodea. Because of its synyonym Orestes verruculatus, it is the type species of the genus Orestes. Because of its compact body shape, the species is sometimes referred to as small cigar stick insect.
