How the first strand of the spider s web is pulled

It's the silk that the spider pulls out in the air.

When it comes to spider webs, many netizens know that it actually looks simple, but after you really understand it, you will find how difficult it is for this spider to build webs, in fact, many people are more concerned about how the first silk is pulled over, spiders don't seem to fly, how to pull from one end to the other? Let's follow me to reveal the secret!

Good question. Many people have been curious about the process of spider webbuilding. This is also a classic question in naturalism, which has been studied by scientists. The results of the observation tell us that, in fact, it is not only the first thread that is difficult to weave, but also the first thread.

Let's start with the first line. The most classic "gossip net" is often woven on two branches or similar empty places. This leads to the helplessness of this line, and how to fix the first two points is very troublesome.

But spiders are smart and take advantage of air currents. They will stand upwind and release a sticky line, which will float to the other side with the help of the wind. Even if the wind is light, it's fine, and the spider silk is light.

When it sticks to another point, the spider can sense it with its good tactile organs, and then pull the thread tightly and hold it in place.

Once fixed, the spider will climb the silk thread. As he climbed, he released new threads to reinforce the first one. This thread is then forced to hang around the net.

When the thread is reinforced, the spider releases a slightly longer thread that sticks to both ends of the first thread. Then go to the middle of the thread, use your own body weight to pull it down, and then release a new thread, pull it down vertically, and stick it to a suitable point below.

After that, the first thread (the reinforced thread is counted), the second thread, and the third thread form a "Y" shaped structure with a top seal. This is the skeleton of the whole web.

After this step is completed, the skeleton is completely built.

Then, a spiral of sticky threads is released from the inside out, and the spider's insect trap web is ready.

This is the most classic way to build a spider's web in an ideal situation, and there will be some differences in practice, and there are many spiders who don't weave such webs, so it's not the same.

The analysis is as follows: the first strand of the spider's web is to fix one end first, and then use its own weight to sag to a certain height, which can make its body like a swing, or use the kinetic energy of the wind to swing itself to the opposite side, and then fix it. This long filament is called a "search filament", and it is left to flutter with the breeze or air current.

After that, the spider will release a dangling silk and add a third silk in the middle of this silk to form a Y-shape, forming the first 3 irregular radii of the spider web, plus more than 50 lines to form the prototype of a web.

The next task is to lay the spiral thread and weave it into a web. Starting from the core of the web, the spider weaves a spiral from the inside to the outside, which serves as the "scaffolding" for the next process.

It should be pointed out that until the "scaffolding" is erected, the web woven by the spider is not sticky, that is, it cannot stick to the insects. At this time, the spider begins to lay sticky silk from the outside to the core of the web, that is, the predatory spiral, and at the same time gnaws and eats the "scaffolding" to complete the final process.

Summary. This is because spider silk is made up of proteins, which contain a substance called "spider protein". In spiders, spider proteins are found in liquid form, and after spider silk is secreted from the gland, it quickly solidifies into solid spider silk in the air.

When a spider is weaving a web, it secretes spider silk through its own abdominal glands, and then uses its legs to pull and position the silk thread, eventually forming a complete spider web. Due to the tiny hairy protrusions and intermolecular adsorption on the surface of the spider silk, it is able to adhere well to other objects. When a spider is weaving a web, it uses its legs and body to pull and position the silk thread, causing it to adhere to the web and form a stable structure.

Moreover, the physical properties of spider silk also allow it to adhere well to other spider silks, resulting in a complex spider web. Therefore, when the spider is weaving its web, its silk thread will also be affected by its own adhesion to keep the web from falling off.
