I saw another question on this site about spiders in cocoons. The answer was that spiders form cocoons to lay eggs. I have observed, however, spiders apparently forming cocoons around themselves, as though to sleep, then they are gone, along with the cocoon, the next day. (I live in Milwaukee, WI, USA.) Are some species of spiders known to form protective temporary cocoons, almost like a sleeping bag, for sleeping or resting? Thanks...

While I am not an expert on spiders, I do remember hearing something about spiders forming cocoons for protection. The also will spin their meal into a cocoon to save for later, and possibly spin themselves in also for protection while eating.
