The spider webs are, both for their architecture and their resistance, a true masterpiece of engineering. These traps are made with more than five types of silk, which differ from each other by their composition based on proteins and water.
However, a spider web always combines at least three of these : a hunting net, made of sticky, stretchy silk; a framework net, with more consistent and less elastic threads; and an anchor net, made of thick and stiff silk. Generally, when an insect collides with the net, it gets stuck in the hunting silk. As he tries to escape, he only gets more and more entangled in the silk trap.
The vibrations make the spider realize that a prey has fallen into its webs and it goes to meet them to inject a dose of paralyzing poison. In its movement, the arthropod avoids stepping on the sticky thread and always tries to circulate through the alternative silk routes.
