Surprisingly, it does not take that long for a spider to create a web. Most spiders do their web-building at night, too, so you don’t often see one in the act of construction. Because wind, large insects, brooms, and other forces and objects destroy webs regularly, spiders rebuild their snares almost nightly. They will eat the old web, almost literally recycling the silk. A few spiders are known to live communally, with hundreds, if not thousands of individual spiders spinning massive sheet-like webs, or building their own webs in extremely close proximity. Communal webs are constantly added to and can cover many square meters.
