Can they even catch anything?

A spider web, spiderweb, spider's web or cobweb (from the obsolete word "coppe", meaning "spider" [1]) 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. The word "cobweb" is usually used for a web inside a house, where dust has gathered on the sticky silk, forming long, hanging streamers.

A lot of "cob webs" are actually "trail lines". When spiders crawl across ANYTHING, they usually have a little safety line going with them. They leave this line behind, it attracts dust and voila -- cobwebs.
