Stick insects in New Zealand are found in a range of different environments, from cold high alpine areas to dry coastal bush. There are currently 23 different species described, from 10 genera ( Landcare Research ). The most common species of the stick insect in New Zealand is the smooth stick insect ( Clitarchus hookeri ) ( Salmon 1991 ). Following Günther (1953), the New Zealand stick insects are placed into the subfamilies Phasmatinae (tribe: Acanthoxylini) and Pachymorphinae (tribe: Pachymorphinini). Classification and identification is based on Jewell & Brock (2002).
This is a list of currently described stick insects in New Zealand:
The Phasmatidae are a family of the stick insects. They belong to the superfamily Anareolatae of suborder Verophasmatodea.
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.
The Phasmatinae are a subfamily of stick insects in the family Phasmatidae. They contain at least three tribes; Bradley and Galil corrected the spelling to "Phasmatinae" and provides a key to tribes.
Acanthoxylini is a tribe of Phasmatodeas. They belong to the "typical" stick insects of the superfamily Anareolatae, though they are rather notable among these. For example, the New Zealand giant stick insect is huge, and all Acanthoxyla are females reproducing by parthenogenesis.
Clitarchus hookeri, is a stick insect of the family Phasmatidae, endemic to New Zealand. It is possibly New Zealand's most common stick insect. Clitarchus hookeri is often green in appearance, but can also be brown or red. Alongside the prickly stick insect and the Unarmed stick insect, C. hookeri is one of three stick insect species to have become naturalised in Great Britain, with all three having originated in New Zealand.
Clitarchus is a genus of stick insects in the Phasmatidae family and Phasmatinae sub-family. This genus is the most common stick insect in New Zealand. It is found widely throughout the North Island and part of the South Island on kanuka and manuka, as well as various common garden plants.
Acanthoxyla is a genus of stick insects in the family Phasmatidae. All the individuals of the species are female and reproduce asexually by parthenogenesis. However, a male Acanthoxyla inermis was recently discovered in the UK, probably the result of chromosome loss. The genus is the result of interspecific hybridisation resulting in some triploid lineages and some diploid lineages. The genus is endemic to New Zealand, but some species have been accidentally introduced elsewhere. The genus name Acanthoxyla translates from Greek as prickly stick.
Acanthoxyla inermis is an insect that was described by John Tenison Salmon 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.
Clitarchus rakauwhakanekeneke is a stick insect that belongs the common New Zealand genus Clitarchus. It lives only on the Poor Knights Islands.
Clitarchus tepaki is a stick insect that belongs to the common New Zealand genus Clitarchus. It is endemic to the North Cape area of New Zealand, in particular Te Paki and the Karikari Peninsula.
Spinotectarchus acornutus is a species of stick insect endemic to New Zealand. It belongs to the family Diapheromeridae, and is the only member of the genus Spinotectarchus. It is commonly referred to as the spiny ridge-backed stick insect.
Niveaphasma annulata is a species of stick insect found in New Zealand.
Megacrania is a genus of the subfamily Megacraniinae of stick insects. Members of this genus are commonly referred to as "peppermint stick insects", due to the characteristic odor of their defensive spray, as well as the cylindrical, twig-like shape of their bodies.
Datamini is the only tribe within the subfamily of the Dataminae from the order of the Phasmatodea. The representatives of this subfamily are on average not as large as those of the other two subfamilies belonging to the family of Heteropterygidae.
Heteropterygini is the only tribe within the subfamily of the Heteropteryginae from the order of the Phasmatodea in the family Heteropterygidae. With 19 representatives described, this subfamily represents both the species-poorest and that of the three subfamilies, to which the largest and most striking species are counted.
Hoploclonia is the only genus of the tribe Hoplocloniini and brings together relatively small and darkly colored Phasmatodea species.
The Obrimini are the most species-rich tribe of the Phasmatodea family of the Heteropterygidae native to Southeast Asia.
Haaniella is a genus of the Phasmatodea family Heteropterygidae from Southeast Asia.
Miroceramia is a monotypic genus of stick insects, containing Miroceramia westwoodii as the only described species. It is the only fully winged one of the subfamily Obriminae.
