Why does the female spider eat the male spider and why does the female spider eat the male spider?

This is because the female spider does not go out to forage for food for about a week before giving birth, and the offspring will guard the offspring day and night for at least a week after birth. The spider will eat within two days at most, just like people, can not stand hunger, but in the lactating female spider, will have super perseverance to endure hunger, and at the same time, the male spider will go out to forage for food, for the female spider to fill the hunger, but this is a drop in the bucket, can not solve the problem, and when giving birth to offspring, it is particularly necessary to nurture to solve the problems of the offspring, and have to take care of the offspring.

Of course, there is no way for the male spider to capture so much food to supplement the nutrition for the female spider, so the male spider will use a miserable way to supplement nutrition for the female spider, it will first bite off its own feet, when all the feet are eaten by the female spider, the male spider is also scorching, and then the female spider will eat the male spider.

And the praying mantis in the animal kingdom will also be like this, the female eats the male.

It is a manifestation of the survival of the fittest in nature and a form of evolution.

Not all females will eat males, and not all females will have the ability to eat males (migratory spiders may have males larger than females).

Female spiders need adequate nutrition before laying eggs, so they will not refuse ready-made food.

Many males (webspiders) kill the eggs laid by females, and female spiders killing males is also considered a kind of protection for young spiders.

Many creatures in nature (carnivorous bugs) are territorial, and any creature that invades the territory can be attacked, and generally speaking, females are larger than males.

Female spiders eat male spiders because female spiders cannot hunt during the breeding period, so in order to be able to give them enough nutrients, they have to eat male spiders.

After the baby spider hatches successfully, the mother spider has not eaten for a long time and does not have the slightest physical strength to hunt, and at this time the baby spider is in urgent need of nutrition, so the mother spider can only feed the baby spider by herself.

Essentially, the mating process between male and female spiders is like a battle, and female spiders are not monogamous.

It doesn't matter who the father of the offspring is, they just want their offspring to have the best genes that can not only eat multiple male spiders, but also increase the probability of survival of the young spiders by mating with more male spiders.

The goal of the male owner is to pass on his genes, and he needs to chase away competitors before mating, so that he can become the father of the female spider to breed offspring.

This is also a picture of the inside of the shell that has been taken off. In the same way, the soft shell of the tail that is glued together is stretched, and then look at the middle of the two small book lungs above, there is no sperm storage bag unique to female spiders, only ordinary like a line, that is the male spider!

Female

This is a picture of the inside of the shell that has been taken off, usually in the tail part of the shell, is soft, and is glued together, you must first open the tail shell before it dries to see the appearance of the picture above. Then there is the place where the arrow is pointing, which is the sperm storage bag that is unique to the mother spider, in the middle of the two small book lungs above.

How to distinguish between male and female of a spider is as follows:

1. Color. The body of the male spider is brighter and shiny, while the female spider is darker.

2. Body type. Female spiders are larger, with thick and powerful tentacles and feet; The male spider is small, with a small abdomen and slender feet, and a thin body.

3. Pattern. Female spiders have only one white pattern, and male spiders have black patterns in their white patterns.

4. Genital poratum. Female spiders have a cover plate outside their reproductive orifices, while male spiders do not.

Spider Sail Species:

1. Bird catcher spider: the whole body is brown, the individual is extra-large, generally about 7 cm long, some can reach 10 cm long, has the ability to build its own nest and walk in the Hui Cave, and many burrows live around the dry field or where weeds grow, lurking in the hole during the day, and going out to hunt at night.

The reproductive ability is very strong, and the amount of poison is also large, each female spider lays 300 500 eggs per year, and every 200 bird-catching spiders can extract 1 gram of poison at a time, which is produced in Guangxi, Yunnan, Vietnam, Myanmar and other countries in China.

2. Chinese tarantula: dense black, white and yellow fine hairs all over the body, ctophorax and back brown, ** with a yellow-brown longitudinal spot. Wide anteriorly and narrow laterally, the middle fossa is distinct, and the body length is 3.4 cm.

For burrowing spiders, they mostly dig burrows and build nests in the fields of cotton, wheat, soybeans and other crops in the plains. It is produced in Shaanxi, Shandong, Henan and other provinces.

3. Rod-linked bride spider: The spider is 3 5 cm long, the back of the cephalothorax is black-brown, the chelicerae are black, the tentacles are yellow, there is a yellow short club-shaped spot on the front half, and there is a yellow checkered spot on the back half, and it is often active in orchards and farmland crops such as rice and corn and forests.

In particular, it is the most distributed in the forest area, often forming complex triple golden webs on plants or tree skills, tying web-type spiders, good at preying on various flying insects, each female spider reproduces 800 900 young spiders a year, and every 400 500 spiders can produce 1 gram of poison. The spider is found in various regions of southern China.

This is because the female spider has to produce more than 100 eggs at a time, which consumes a lot of food, and the food is not easy to catch, so the male spider has to be sacrificed to nourish the female spider.

Female spiders eat male spiders because female spiders cannot hunt during the breeding period, so in order to be able to give them enough nutrients, they have to eat male spiders. After the baby spider hatches successfully, the mother spider has not eaten for a long time and does not have the slightest physical strength to hunt, and at this time the baby spider is in urgent need of nutrition, so the mother spider can only feed the baby spider by herself.

The male spider provides the required nutrients to the female spider, and the female spider provides the required nutrients to the small spiders. Female spiders are pregnant and do not prey, so they will eat male spiders. The baby spider eats the mother spider for the first time when it is born, and it does not prey!
