Spider's web , state of art

A spider web, spiderweb, spider's web or cobweb (from the obsolete word "coppe", meaning "spider" sometimes with the connotation of being a dusty, abandoned web) is a device built by a spider out of proteinaceous spider silk extruded from its spinnerets.Insects can get trapped in spider webs, providing nutrition to the spider; however, not all spiders build webs to catch prey, and some do not build webs at all.
