Acanthoxyla prasina or prickly stick insect is a stick insect in the order Phasmatodea and the family Phasmatidae. It is found throughout New Zealand, although it is less frequently reported than "common" stick insect species. It has a thorny skin, which is used as camouflage. The species reproduces by parthenogenesis, producing eggs without the help of a male, and no male prickly stick insects have been found. Although native to New Zealand, the insect has been accidentally introduced into England, where it breeds well.
