What are the sentences describing cobwebs?

Spiders have a small head, a big belly, a black appearance and eight ugly legs. It is really ugly, but it is a "hero" who catches mosquitoes and flies and is indeed our friend.

The spider hid under a leaf, and looked at his newly woven web with small eyes, as if admiring some artworks.

When the hot summer comes, a spider comes to my window. I've always been interested in spiders, so I watch them carefully. Spiders mostly weave webs in the morning. When flies and mosquitoes try to sneak into my house, they will bump into a sticky and strong net. They struggled desperately to escape, but it was impossible. The spider saw it from the side, as if thinking, "Stop struggling, you brought me something delicious." But spiders can't eat them right away. It spits out a mucus from its mouth to soften the flying insects and then slowly eats them.

Although the spider is not beautiful in appearance, it has a set of skills to kill pests for people. Spiders have mucus in them. It will suck the mucus out of their tails. When it meets air, it becomes elastic viscose. It often bridges between two bare trees: climb the tree slowly and steadily, pull out a mucus-silk, and then pull the silk to climb to the opposite tree. After building a bridge at high altitude, I began to weave a net. Round after round, one after another, just like a skilled girl weaving a web. Soon, it was woven into a net like an octagonal kite. It is obviously a little tired, so it hides aside to rest and watch, waiting for flies and mosquitoes to trap itself!

I caught a Okumo with black and white stripes on his back, with gray dots between the stripes. It looks as if it had been oiled. I put it carefully in the specimen box.
