Why Spider does not fall into the net own?



Why Spider does not fall into the net own?
To answer this question we must first examine the miracle of spider web engineering. In terms of thread strength, the silk threads that make the fabric stronger than steel are only stronger than the molten quartz, and the thread extends to five times its length before it breaks.

In fact, this small thread that appears in front of the naked eye is made in the same way as the coal cable, which consists of several tiny strings wrapped around each other, and the thickness of one thread may be 1 millionth of an inch. Materials of manufacture are very common, with one hectare in one of the British provinces, for example, more than two million and a quarter of a spider. Each spider has its own spindles, usually three. This is a natural spindles found the lower abdomen . Near each spindle there are small gland openings from which the silk thread, a substance formed in the spider's glands, emerges. During fabric engineering, the spider collects all three threads together to form a strong, strong stalk.

Spiders living outside the house spawn a kind of fabric known as the astronomy in relation to its circular shape, a remarkable geometric piece of harmonized lines that appear so beautifully in the early dawn. And female spider takes care of building the web . She uses her stomach pressure to push the thermal threads out of the six glands in her abdomen, and she ties the end of the first thread, known as the bridge, to a branch of a herb, or a leaf. And then descend to the ground with the truss, continuing the process of knitting, and then descend to the ground and climb to another high point, to pull the string strongly, and connect it in place well using adhesive sticking out of one of its glands as well. First, you install a string, always horizontally, and then fall two silk threads at each end of the first thread, to form other bridges lower than the first, which will become the basis of the work network. Then you thread several threads inside this work network, and all the threads meet in the middle. Here comes the smart work, where you put the adhesive on the outer threads of the network only, and when you finish the completion of the network complete the process of putting the glue inside and on some sections only to leave a place to move it easily.

After the network is completed, the spider makes a small nest nearby, usually rolls a leaf and puts inside itself a comfortable bed of silk. Because of course she may wait a long time before the arrival of her first victim.

Finally, you attach a thread of warning between the nest and the fabric, so that you feel any vibration may occur on the fabric as a result of the fall of any insect it. When this vibration occurs, accelerate to the center of the fabric to see what you are going to handle. Because of the severe visual impairment, the spider will rely on its other senses to determine prey characteristics. If it is huge and deadly, it will be released from afar. If it is large and not eaten, like the dragonfly, it will be wrapped in silk threads from afar, using another specialized organ, the cluster-shaped gland. The insect persecutes itself by trying to get rid of the polytheism. The spider then begins to progress towards it through the safe threads that it left itself without adhesive. If it accidentally misses its feet and puts its feet on the adhesive, its body will secrete a substance that acts as a chemical chemist for glue. .

You may not like spiders, but when you think of their ability to destroy insects and clean up their farm places, you will not underestimate them anymore.
