Walkingsticks belong to the order Phasmida, named for the Greek word “phasma,” which means apparition or ghost.
Walkingsticks are capable of autotomy, which means that they can regenerate lost legs. If a walkingstick is grabbed by the leg by a predator, for instance, the leg will come off, allowing the insect to escape. Through successive moults, a whole new leg, albeit slightly shorter than the original one, will grow back. This phenomenon is called regeneration.
In addition to reproducing sexually, walkingsticks are able to reproduce by means of parthenogenesis: females can lay fertile eggs without being fertilized by a male. Such eggs produce only females.
In the 1800s, a naturalist predicted that by the year 2000 people would be raising walkingsticks as household pets.
