The mantises are an order of insects containing over 2,400 species and about 430 genera in 15 families. The largest family is the Mantidae. Distributed worldwide in temperate and tropical habitats, mantids have triangular heads with bulging eyes supported on flexible necks, and elongated bodies with or without wings. All mantises have greatly enlarged forelegs adapted for catching and gripping prey; their stationary upright posture, with forearms folded, has led to the common name "praying mantis". They are mostly ambush predators, but a few ground-dwelling species actively seek prey. They live for about a year; in cooler climates, the adults lay eggs in autumn, and die. Protected by their hard capsule, the eggs hatch in the spring. Mantises are sometimes confused with stick insects (Phasmatodea), other elongated insects such as grasshoppers (Orthoptera), or other insects with raptorial forelegs such as mantisflies (Mantispidae). Mantises were considered to have supernatural powers by early civilizations, including Ancient Greece, Ancient Egypt, and Assyria. They are among the insects most commonly kept as pets.
