What's the difference between a spider web and a cobweb?

"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. However, the word "cobweb" is also used by biologists to describe the tangled three-dimensional web of some spiders of the family Theridiidae.

They spin an upright silk tube and hide inside it. When an insect lands on the outside of the tube, the purse web spider cuts the silk and pulls the insect inside.

Where does the protein in spider silk come from?

How long does it take for a spider to recycle silk?

  • Spiders will often recycle valuable silk proteins by eating their webs. Scientists have labeled silk proteins using radioactive markers and examined new silk to determine how efficiently spiders reprocess the silk. Remarkably, they've found spiders can consume and reuse silk proteins in 30 minutes.
