Habits of China mantis

Mantis, also known as knife mantis, is an invertebrate and belongs to Mantidae, a winged subclass of Insecta. It is a medium to large insect with a triangular head, which can move freely, and its compound eyes are big and bright. The antenna is slender; The neck can rotate freely. The leg joints and tibial joints of the forefoot are prickly, and the tibial joints are sickle-shaped and often fold to the leg joints to form the forefoot that can catch prey; The anterior wing cortex is covered with wings, lacking the anterior domain, the posterior wing is membranous, and the gluteal domain is developed into a fan, which folds on the back at rest; Abdominal hypertrophy. Except in extremely cold regions, it is widely distributed all over the world, especially in tropical regions. There are about 1585 species known in the world. About 5 1 species is known in China. Among them, southern mantis, northern mantis, broad-axe mantis, Chinese mantis, European mantis and green-spotted mantis are important natural enemies of pests in agriculture, forests, fruit trees and ornamental plants in China. Mantis is very long, mostly green, but also brown or spotted. The compound eye was prominent, with 3 eyes in one eye. Chew the mouthparts, and the upper jaw is strong. Grasp the feet with the front feet, and the middle and rear feet are suitable for walking. Gradually pervert. Eggs are laid in egg sheaths, and there are 20 ~ 40 eggs in each egg sheath, arranged in 2 ~ 4 rows. Each female insect can produce 4 ~ 5 egg sheaths, which are hardened by foamy secretions and attached to branches, bark, walls and other objects. The newly hatched nymph is a "pre-nymph", and it will become an adult only after peeling for 3 ~ 12 times. Generally 1 year 1 generation, some species parthenogenesis. Eating meat and hunting all kinds of insects and small animals can eliminate many pests in fields and forest areas, so it is beneficial. Sexual abuse and aggression, lack of food often lead to the phenomenon of swallowing snacks and females eating males. Individual species distributed in South America sometimes attack small animals such as birds, lizards or frogs. Mantis has protective color, and some are mimicry, which is similar to its environment, thus preying on a variety of pests.

The English name is mantid. Also called mantis, mantis or mantis. There are nearly 2,000 species of large fast-moving insects in Mantidae, which are characterized by a long chest (upper part), a groove on the ventral surface of the thigh joint of the forefoot, spines on both sides of the groove, and the tibiofibular joint (lower part) can be embedded in the groove. It only eats live worms and holds its prey firmly with its prickly front feet. When you are frightened, your wings will rustle and you will show a bright warning color. Common in plants rather than on the ground, the shape can be green leaves or brown dead leaves, twigs, lichens, flowers or ants. Relying on mimicry can not only avoid natural enemies, but also be difficult to be found when approaching or waiting for prey. Females often feed on males after mating, and the eggs laid in the egg sheath can protect them from bad weather or natural enemies, and the number of eggs is about 200. Nymphs (wingless adults) hatch at the same time and often kill each other.

Mostly distributed in tropics and subtropics. The representatives of Europe are mantis (religious mantis [is the most widely distributed species]), Ameles, Iris and Empusa. North American genera include stagno Mantis (S. Carolina), Litaneutria (L. minor is a small western species, the only mantis native to Canada), Thesprotia (slender) and Oligonicella (slender). Mantis gracilis, Iris Millennium, Pelargonium angustifolia and Pelargonium chinense have been introduced to North America. China mantis is very common in China. It is native to many places in East Asia and is the largest mantis in North America, with a body length of 7? 6? 5 10 cm.

The English name of "mantis" comes from Greek, which means "soothsayer", because the ancient Greeks thought mantis had supernatural power. The current name "mantid" (Greek meaning "fortune teller") also reflects this view. Mantis can stand still or swing gracefully back and forth, raise its head and stretch out its front feet as if praying, from which many myths and legends are derived. According to superstition, mantis's brown saliva can make people blind, and horses or mules will die if they eat mantis. The English common name "praying mantid" and scientific name "Mantis religiosa" of Mantis, as well as its German name "Gottesanbeterin", French name "prie-Dieu", Provence name "prega- Ou Di" and West Indies name "Shenma" are all related to religious piety. Other common names include "devil's horse", "mule killer" and mantis religion. Since all mantis are fierce carnivores, it is more appropriate to describe them as "preying" than "praying".
