Bob the spider comes back every night, builds his rather large web over the sliding door, and eats the bugs that come to the lighted glass. Every morning, he takes the web down like a good little spider and retires into the woodwork so that I can exit the house to water the plants. Bob, having impressed me with his courtesy, and being anyway outside the glass, is exempt from the Wiggler Compact (the Wiggler Compact being that if it comes in the house and I see it, it dies.)
What does he do with the silk he takes down? Every morning he quietly demolishes a rather large web at least two feet in diameter. I realize that spider silk is unbelievably thin, so he could just be making a teeny tiny ball and dropping it, but I wonder. Does he eat it? Play with it? Save it for later? Where does the used silk go?
