Stick Insects (Phasmatodea)

Over 3,000 species of stick insects are found worldwide in tropical and subtropical environments, with some found in temperate environments. Stick insects, also called walking sticks, are herbivores with chewing mouthparts and are usually active at night. During the day they tend to remain camouflaged on plants to escape predators, and will often sway side to side as if caught by the wind. Their eggs are also camouflaged and resemble seeds. Some species can lose their legs in response to predators. The lost leg will continue to move distracting the predator away from the escaping insect. These species can usually regenerate that leg if they have more molts to undergo. Some species can reproduce without males, but will only have female young when they do so. Most stick insects can live up to three years.
