BACKYARD SECRET: The Secret of the Vanishing Spiderweb

Have you ever found a beautiful spiderweb one evening and returned the next morning to admire it in the sunlight only to find that it had mysteriously disappeared?  When you have such an experience, you cannot wonder what in the world happened to this remarkably structure.  The answer to this mystery is perhaps as odd as the disappearance of the web itself.

Surprisingly, in many cases, the web is simply eaten by its creator.  If that is the case, you might ask yourself, “Why in the world would a spider eat a web it only used for a few hours and required a lot of time and energy to fashion?”    Part of the reason is webs lose their stickiness.  As a result, they hapless insects that would normally find them stuck in a web are able to struggle free before the spider can dispatch them.  Also, if a spider eats its own web, it recycles some of the energy and protein used to spin the sticky strands used to weave its beautiful and deadly web.  In addition, it ensures that each night it is using a fresh, highly efficient web.
