The Phasmatidae are a family of the stick insects (order Phasmatodea). They belong to the superfamily Anareolatae of suborder Verophasmatodea.

Like many of their relatives, the Phasmatidae are capable of regenerating limbs and commonly reproduce by parthenogenesis. Despite their bizarre, even threatening appearance, they are harmless to humans.

The Phasmatidae contain some of the largest insects in existence. The recently discovered Chan’s megastick (Phobaeticus chani) of the Clitumninae can grow to a total length of over 0.5 m (20 in); it is the longest living insect known.

Walkingstick, also called stick insect, any of about 3,000 species of slow-moving insects that are green or brown in colour and bear a resemblance to twigs as a protective device. Some species also have sharp spines, an offensive odour, or the ability to force their blood, which contains toxic, distasteful chemicals, through special joints in the exoskeleton. In many species the eggs closely resemble seeds.

Life Cycle

While mating, male and female walking sticks can attach for many hours, several days or sometimes weeks. During this time, the male, who is usually younger than the female, can protect his partner or, at least, his sperm is putting many eggs every day, combined with bark of the home plant and leaves, can bury them in the soil, or They can discharge them into leaf waste.

Female eggs, which are closely related to its main host plants, have lid structures, depending on the species and conditions, the buffaloes will be raised in the months or even years. Typically, the walking stick will live for a year, but it can live for many years, especially in captivity.


They live in most parts of the United States, which are the highest in the southern part of the country. Species make their homes in select plants. For example, southern California and Arizona’s Western Shinggun Sticks live in their favored globe, Molo and Bourlin.

Texas’s giant stick insects prefer with their favorable oaks and grapes stalks from the bottom of the river. Walking sticks can feed on one leaf plant or one of the different leafy plants, the favorite species. In heavy plight, walking sticks can ruin the food plant, however the pest reach is usually limited by the absence of the wings.


  • Approximately 1 in 1000 stick insects is male
  • The walking stick is the longest of all the modern insects, with a documented specimen from Borneo, for example, measuring more than 18 inches in length.
  • The giant walking stick, Megaphasma denticrus, which ranges from New Mexico eastward, is perhaps the longest in the United States, measuring six or seven inches in length.
  • Lacking a partner, a female walking stick can still lay fertile eggs, although all will yield female larvae. (Animals that can reproduce asexually are described as “parthenogenetic” by biologists.)
