Science 101: Why Don't Spiders Stick to Their Own Webs?
Robertson, Bill
Science and Children, v49 n1 p68-69 Sep 2011
This article explains why spiders don't stick to their webs. Spiders don't get stuck in their own webs (and they aren't immune to their own glue) because they use a combination of sticky and nonsticky threads (different glands for producing those), and the glue is in droplets that the spider can avoid but the prey can't. The spider's nervous system is hardwired so the spider knows how to avoid the sticky threads and how to avoid the droplets. (Contains 1 figure.)
