Mantis is is an insect (Datura), which contains more than 2400 species in 430 genera of 15 families. The largest family is mantidae ("mantids"). Mantis is distributed in temperate and tropical regions of the world. They have triangular heads and bulging eyes that support their soft necks. Their slender bodies may or may not have wings, but all mantodya have forelimbs, which are greatly enlarged and suitable for catching and catching prey. Their upright posture, while their forearms remain stationary when folded, led to the common name of Mantis.
The close relatives of Mantis are termites and cockroaches (Blattodea), both of which belong to hyperptera. Mantis is is sometimes confused with a bamboo moth (Phasmatodea), other slender insects (such as Tetrix (Orthoptera), or other insects unrelated to the forelimbs of the UN genus (such as Mantis). Mantis mainly ambush predators, but some species that live on the ground are actively pursuing their prey. They usually live for about a year. In a cool climate, adults lay their eggs in autumn and then die. The eggs are protected by hard oocysts and hatch in spring. Females sometimes engage in cannibalism and eat their partners after mating.
Mantis is is considered to have supernatural power by early civilizations including ancient Greece, ancient Egypt and Assyria. A popular cultural saying in cartoon caricatures imagines female mantis as the beauty of snake and scorpion. Mantis is one of the most commonly kept insects as pets.
The mantis has a large triangular head with a beaklike nose and mandible. They have two bulbous compound eyes, three simple little eyes and a pair of antennae. The joints in the neck are also very flexible; some mantis can rotate the head nearly 180 degrees. Mantis chest is composed of front chest, middle chest and back chest. In all species except for the genus mansoni, the thorax with head and forelegs is much longer than the other two thoracic segments. The front chest also has the flexibility to engage in joint movement, allowing for extensive head and forelimb movement, while the rest of the body remains more or less motionless.
The forelimb of a mantis, holding a long spike
The mantis has two spiny, grasping forelegs ("Raptor legs") in which prey is firmly held and held. In most insect legs, including the last four legs of the mantis, the tailbone and rotor are the inconspicuous bases of the legs. However, in the arched leg, the hip joint is combined with the trochanter to form a segment as long as the femur, which is a spike part of the gripping device (see Figure). A group of discoid spinous processes are located at the bottom of the femur, usually in the number of four, but depending on the species, from none to as many as five. Before these spinous processes, there are many dentate nodules, together with a series of nodules along the tibia and a tip claw close to its tip, so that the mantis's forelimb can catch prey. At the end of the forelimb is a small bone, which is used as an appendage of walking. It consists of four to five parts, and at the end is a two toed claw without a phalange bone.
Mantis can be roughly divided into big wings (long wings), short wings (short wings), small wings (wings) or (wingless). If not wingless, mantis has two sets of wings: the outer wing is usually narrow and leathery. They act as shields for camouflage and rear wings, which are clearer and more delicate. The abdomen of all mantis is is composed of 10 tails, 9 holes in male and 7 holes in female. Men tend to be slimmer than women, but in both men and women, the abdomen ends in a pair of waxes.
