Photo de stock - A spider web, spiderweb, spider's web or cobweb (from the obsolete word coppe, meaning ""spider"") is a device built by a spider out of proteinaceous spider silk extruded from its spinnerets. Spider webs have existed for at least 141 million years, as witnessed in a rare find of Early Cretaceous amber from Sussex, southern England.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. ""Spider web"" is typically used to refer to a web that is apparently still in use (i.e. clean), whereas ""cobweb"" refers to abandoned (i.e. dusty), webs
