How do spiders elongate and wrap around? How do spiders build webs?

The elongated web of the spider relies on the wind to blow through, but the method of blowing through is a bit special.

The spider finds a foothold from a tree, and draws out many filaments long enough to reach the opposite side, so that these filaments float in the wind, and then it touches the anchorage point of the spider's silk with its feet at all times. If any of the threads can't be pulled, then the threads are already wrapped around the trees opposite, and the "heavenly rope" is erected.

Like the pillars of a house, it sticks a few more strands back and forth on this supporting line that is bound to be a spider's web, making it into a thick "cable". Then, under this thick "cable", a second "cable" was erected in parallel. The spider crawled around, and the web was erected on these two "cables".

How the spider stretches around well, the spider itself will spit silk, so he is. Yes. Pull a very long filament. Long. And then. Round and round.

There is a bump in the spider's abdomen, called a spinning machine, which secretes a kind of mucus that turns into extremely fine silk when it encounters air, and these silks are the main material of spider webs.

When weaving a web, the spider first fixes the spit silk at one point, then hangs itself on the silk, and crawls to the opposite corner of the house or branch while spinning the silk, and uses its feet to fix the silk at another point. Then, the spider will go back and forth, repeating the same action until the vertical threads are all weaved.

Then, the spider will return to the axis, take the axis as the midpoint, and slowly weave a horizontal line along the shaft pulled by the vertical line, using filaments that are barely visible to the naked eye around the vertical line. This area made of filaments is the spider's resting area.

Once the rest area is set up, the spiders begin to weave the capture area with thick silk until a beautiful spider web is formed. After the web is woven, some spiders will also pull a thread under the web to make the web stronger.

It will take advantage of the airflow. 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.

Not only is it difficult for the spider to build a web, but also for the second one, and after the first one is pulled, the spider will release 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.

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 droop 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.

When a spider builds a web, how does the first line get to the other side?

Well, I've seen it, and it's amazing, that the spider just spews out a wire that pulls out, and the wire that touches the opposite side sticks on, hehe, the spider is amazing.

There is a cross between the two points! Inside a house, they're going to climb over the roof, or the branches of a tree, and they're at an intersection of the planes.

Spiders spin silk, spiders can jump.

Climb over, or choose the direction of the wind when the wind is strong.

The tail of the belly of many spiders.

The bai part has a special structure - textile zhiqi. The weaver produces a special type of slime that shoots out from the six inner holes in the tail.

As soon as it comes into contact with the gas in the air, it will harden and become both elastic and strong spider silk, some of which are elastic and some are not.

When spiders build webs, they often spit out a few slender wires first, and rely on the wind to blow them, fix these long filaments at one point, form a square row or irregular outline, and then form a radial web from the center point to the outside, these threads are sticky and are insect trappers.

Most spiders catch their prey by weaving webs. So how exactly do spiders weave their webs? The spider's abdomen has a raised organ called a spinl.

It can secrete a type of mucus. This slime condenses when it encounters air. This is the main material of spider webs.

Most spiders weave webs, but there are also spiders that don't, such as tarantulas.

Start by pulling several warp threads, then run to the other end and repeat the same motion. The warp threads are pulled evenly at both ends, so that the net threads are tighter and more evenly distributed.

When the warp threads are all knitted, the spider returns to the axis to rest, and then works on the weft threads along the wheel shaft pulled by the warp threads.

The spider takes the axis as the midpoint, and uses filaments that are barely visible to the naked eye to slowly weave horizontal threads around the warp. Each line is carefully spaced. This filament-woven area I call the "rest area".

After the rest area was built, the spiders began to pull the thick silk, which was visible. It can adjust the thickness of the silk thread arbitrarily, and use the spiral weaving method to pull the distance between the thick weft threads.

Await. Wait for the wind to blow the spider silk through.

I don't know where the upstairs is coming from, at least for me.

The spider webs observed are not quite the same as those described upstairs. The spider webs I have observed are usually pulled out of the longest fixed wire, which is the longest of all the warp threads of the spider web, and it fixes the position of the lower web. Once the thread is fixed, the spider pulls out several strands outward at the tip of the thread, which can be attached to adjacent branches or leaves with the help of wind or the spider's own bounce.

When these are fixed, the spider begins to formally form a web. When spiders build webs, they do not eat the dried silk after pulling it, as the upstairs said, but weave a frame with dried silk and fill it with sticky silk. When spiders walk on the web, they choose dry silk to walk.

It takes about 2 hours for spiders to form webs, and some species are even slower.

It's a very long, long silk thread, and then a diagonal line, and then another one, and then you pull the net around this cross-shaped line, and that's how it works.

You surf the Internet every day, you don't know it, take a look at it.
