Is spider weaving webs unconscious, and why do they mend them? 10

This question may seem simple, but it actually involves knowledge of animal genetics, evolution, and behavior, and I try to explain it in non-professional language.

Spider web-weaving is a subconscious act. The subconscious is not the same as the unconscious, that is, spiders are born to weave webs, and they do not consciously know the meaning of web-weaving, but only associate webs with food. Just like a baby will suck after birth, such an action does not need to be taught, which ensures the survival of the baby, if the baby does not suck, it needs to be mastered through learning, and before the baby learns, he will starve to death.

Spiders don't bend their webs on purpose. The action of their webs is coherent, for example, just like a person who knows the order of counting from 1 to 10, but does not understand the meaning, telling him to count from 10 to 1, he will not be able to, spiders weave webs in one go, follow a fixed order, if the web is destroyed halfway, it will only start all over again, that is, sometimes we see that the continuous repair of the web, in fact, it is in the original net to re-weave a new web, not just to repair the broken part.

Some literary works will use animal examples to inspire people, but they are all based on subjective anthropomorphism and do not conform to objective facts, so we should distinguish the difference between literature and science.

Spider weaving webs is an instinct of animals, which cannot be said to be unconscious, in order to survive, in order to better capture prey, it has to constantly replenish its webs.

There are only two reasons for spiders to build webs, one is that they can have a place to settle down, which can play a role in protecting themselves. The second is that the web can be used to capture prey, which is the main means of predation, as long as the insect is on the web, it is difficult to break free, and eventually becomes the food of the spider to provide nutrition. <

Reasons why spiders weave webs:

1. Prey on prey.

2. Survival needs.

Spider web-weaving is an inherent ability in itself, which is innate. But for spiders, weaving webs can be called a very complex mental and physical work, from the design of the web, the selection of the location, to the on-site construction work, it is difficult for idle people to do it. Therefore, there are many species of spiders such as tarantulas, jumping spiders, crab spiders, etc., which do not form webs to this day, and they usually hunt and hunt.

But if we go back to the ancient times when spiders originated, it is not difficult to find that the ancestors of those spiders that can build webs, such as garden spiders, should also not be able to build webs, and the spider's instinct to weave webs should be created by their ancestors through the survival practice of a long time, that is, the spider's instinct can only come from the three survival practices of survival competition, species competition and reproductive offspring to adapt to nature.

Definitely, but only about half of all spiders weave webs. Some spiders spin silk to help escape, such as spinning silk wraps to protect themselves, and hanging a silk from the ceiling to the air or the ground. What's the secret of spider spinning?

Different spider silk has different characteristics such as strength, elasticity and toughness, but through research and comparison with natural materials and synthetic materials, it is found that spider silk is much stronger than them, and the tensile strength of each spider silk is twice that of steel, and the elasticity is much better than that of man-made fibers. For example, a spider web can extend up to 10 times its original length, while nylon breaks once it reaches 20 times its original length.

Through observation, it is found that each spider is followed by a spider silk, which we call traction silk, which can be said to be the lifeline of the spider and plays a very important role in the spider. When the spider falls from the top of the cover, it acts as a safety rope to ensure the safety of the spider's life; When the spider encounters danger, it acts as a ** line to transmit an alarm to the spider in time to ensure that the spider escapes in time; At the same time, the most important radial radius line of the spider web is also composed of traction wires.

The same question, copied from the answers of my other friends to show you.

Common garden spider (see the big spider in the tree or in the community in normal summer) web-building process:

1.A commanding height, on which the spider is located, the spinning extracts a liquid that condenses into a solid filament when it encounters air2West four drifted with the breeze to another commanding height not far from the fingerwheel, and the adhesion was completed, 3

After the main filament is adhered to, the spider will only stick a very thick and strong silk at the origin, which is the most critical silk of the entire spider web, and the spider spinner will stick the head of the silk to the origin, and then the spider will float along the filament to another point, colleague, the very thick and strong silk has also passed together, this is the completion of the trunk, 4The spider crawls to the middle of the trunk and naturally hangs down to the third point, so that the big repentance frame of the web is completed, and the next thing is what the friend below said.

The spider's silk meets the air and condenses into solid silk threads. Tough, spiders are covered with bristles and oil glands on their own body surface, which play a role in preventing sticking and also play a good role in rubbing.

It varies from spider to spider, and if you put a bird spider on the web of a garden spider, it will also get sticky.

Depending on the type, the quality of the silk thread is also different.
