Why is a spider s web not checkered?

After countless observations and studies, people have discovered the pattern of spider webs.

The spider first fixes some silk around the branches and corners of the wall. Among them is a special filament, which is woven with a little silk into a white dot in the middle through the surrounding area, which is the center of the net. So it hung a wire from the side and walked along the knotted wire, walked to the center, and then tightened, and the excess length gathered on the white spot of **, and then from ** to the edge, plus some spokes, in turn.

When it adds a few spokes on one side, it goes to the opposite side to add a few spokes to maintain balance. The spokes of the spider divide a circle into equal numbers, and the angles between each two adjacent radii are about the same. After pulling a circle with many equal radii divided, it circles outward from the center, and makes a spiral on the radius with a very thin filament, circling outward from the center, and parallel to each other, but the spiral to the periphery is thinner than the other.

2] The spider will first release a long "search wire" into the air, which will be left to flutter in the breeze or air current. After that, the spider will release a hanging silk and add a third silk to the middle of this silk to form a Y-shape, forming the first 3 irregular radii of the spider web. In addition, more than 50 lines form the prototype of a net.

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". The latter process. [1]

The spider first has to build a framework as a foundation. Spiders with this kind of frame often show very amazing skill. After choosing a location, it first pulls a horizontal, assuming that it is from A to B, and then it pulls a vertical from B to C, and then from C to D, parallel to the first horizontal (that is, A and B).

Finally, one of the vertical strips from D to A and parallel to the second straight (i.e., B and C). This creates a square frame. Of course, the spider doesn't necessarily build a full square frame, but it always does it that way.

1] The spider's superb web-building ability is due to the fact that it uses itself as a measuring instrument to determine the mechanical movements and positions of the two pairs of feet and the textile process, so it can weave such a well-defined silk web. After the spider has formed a web, it sometimes squats in the center of the web; Sometimes it hides in a hidden place, and a "signal" line leads from the center of the net to its side, and receives the "signal" from the net at any time, and hunts food accurately. [2]

The style of square things is generally not easy to calculate and make, and the circular pattern is faster and easier to complete.

The purpose of spiders to build their webs is to hunt. This also has to do with the body structure of the spider, otherwise it would not be able to survive.

Spiders are born to build webs, just as monkeys will go up trees, rats will burrow, sows will arch the ground, and people will go online.

Hello dear, it's a pleasure to answer your questions, spiders like to build webs in corners. Because the relative area in the corner is relatively small, there are more connection points, and it is easy to form a network. It is also convenient to build your own nest to live in this place, and there are generally more flying insects in the corner, and the spider's food is more abundant.

That's why spiders like to build webs in corners.

1. The round web, also known as the Bagua Array, is a regular spiral structure with a skeleton network, and generally large outdoor spiders (garden spiders, etc.) often form this kind of web.

Rotary screen. 2.The irregular sheet web, which looks disorganized, is actually a grid area within the plane of an acorn, but the mesh shapes and sizes are different, such as ghost spiders.

A chaotic and irregular web.

3.The dish webs are also irregularly distributed, but the middle will be significantly lower than the surroundings, forming the shape of a dish, such as the outdoor pastoral spider.

dish nets. 4.The funnel web, surrounded by an irregular structure, is only denser, and has a tubular structure for escape, looking down from above, as if there is a hole, such as a labyrinth funnel spider.

Funnel web. 5.Irregular stereo nets.

Also known as the suspension bridge to make such a tung web, on the basis of the irregular sheet web, there are more three-dimensional support wires, that is, three-dimensional webs, Australian black widow spiders are best at knotting this kind of web, if the ghost spider is placed in a small space with a certain height, it will also be forced to knot three-dimensional webs.

6.Radial stereoscopic nets.

It is also an irregular structure, but it has a distinct three-dimensional structure and is radial.

7.Curtain net. It is also called the dome net, which is about the same as the funnel net, and the irregular structure is like a tent.

8.Wheel netting.

It is also regular like a rotary net, but does not have a spiral structure.

Wheel mesh and radial three-dimensional net, the farther is the wheel net.

There are spiders that do not form webs, such as tall spiders.

Prowling spiders do not build webs, but wander around or camouflage in place to hunt prey, such as tall spiders, which are commonly known in Taiwan (worm na) (insect forehead). The tall spider is a burrowing spider that is larger than a dinner plate. The 30-centimeter-long giant spider (Heteropoda maxima) is the world's largest tall spider and has a ferocious appearance that preys only on large insects.

Although not much is known about its behavior, it is known to move quickly and have a venomous sting.

The tall spider is an animal of the genus Cancer in the family Canceraceae. It is widely distributed in the world, Taiwan and Sichuan, Guangdong, Anhui, Zhejiang, Hubei, Hunan, Jiangxi and other places in Chinese mainland, and often inhabits indoor and outdoor walls. The type origin of this species is Europe.

It is a large indoor spider that does not form webs and is the main natural enemy of household cockroaches.
