Mantises, also known as knife mantises, are invertebrates, belonging to the insect family, winged subclass, mantis family, is a medium to large insect. In addition to the polar regions, it is widely distributed all over the world, especially in the tropics. Mantis is carnivorous, fierce and aggressive, with a wide range of food and a large amount of food, preying on many pests in agricultural and forest areas, and is an important natural enemy of pests in agriculture, forestry, fruit trees and ornamental plants.
According to records and legends, male mantises ask the female mantis for pleasure at the cost of their lives. Before mating, the male praying mantis carefully and secretly approached the female mantis from behind, crawled and stopped, and it took nearly 1 hour to sneak to the mother mantis in fear, and summoned up enough courage to suddenly hold the female mantis's body to mate with it. Just as the male mantis was shaking, the female mantis turned back like lightning and bit the male mantis's head and ate it into its stomach. The male mantis knows that the female mantis will eat himself, and he bravely goes to bathe and fall in love with the female mantis, which is really a terrible thing.
Some animal behaviorists explain that the female mantis is not angry with the male mantis for violence, burning in anger and killing the husband, but to stimulate the male mantis nerves and ensure that semen is continuously injected into its body. They believe that the center of inhibition of the male mantis nervous system is in the head, and once the male mantis loses its head, it also loses its inhibition function, and the semen in the body of the male mantis without a head will flow into the female mantis to ensure the fertilization of the egg. While mating, the female mantis bites from the head of the male mantis to the tail until the male mantis abdomen, at which time the female mantis is not only full, but also the eggs in the body are fully fertilized, and the eggs that have been rich in nutrients can be laid.
Are there any other reasons? Scientists have once observed the tailing of large knife mantises in the laboratory. They feed the mantises beforehand, turn on the lights, and watch from the side, allowing the mantises to have fun without privacy. Unexpectedly, in thirty mating sessions, the male mantis does not complete mating work until the head is bitten off, as is written in some insect books. They observed that the male mantis was able to mate without being bitten, and on the third day after mating, the female mantis did not eat or bite off the head of the male mantis in the mating.
As a result, some people think that male praying mantises may have survived if they had not lost their vigilance, which is really incredible. Coincidentally, a few years ago, the United States published a textbook entitled "Sex and Death: An Introduction to the Philosophy of Biology." Why did you use such a title? The author explains that "for sex and death are eternal themes of the biological world" and that "the biological world is wonderful and eccentric, at least more eccentric than we can imagine".
It can be inferred from this that ease and pleasure are like a soft knife, so that the praying mantis gradually wears away its will in a relaxed and comfortable state, loses its vigilance, and unconsciously dies in the land of gentleness, which is the so-called "fame and poverty, when the failure is proud".
This is true not only of praying mantises, but also of people, and of social development. If Tai reaches the extreme, it will come; if it reaches the extreme, Tai will come. Therefore, the most dangerous and terrible time in life is not the time of frustration, but the time of pride. Because of the arrogance, because of the wisdom of Li Ling.
