because the spider can sit and wait until their food are there.
AnswerNot all of the strings in the spider's web are sticky. The spider knows which are which and they move around by walking on the nonsticky ones. Thats right. Spiders do produce two entirely different "types" of thread. They use the non sticky threads as spokes to move around their web while they build the proper sticky bits.AnswerA spider has special glands that produce an oil like material that does not stick to their own web. I am guessing these are located somewhere near their feet since these are the parts that come in contact most with the web. Not really an answer, but still!Next time you see a spider web, try touching the very center of it where the spider sits. It shouldn't be sticky. Also, when the spider is in the web, try plucking the threads. The spider will come rushing to that point to fix it.
Spiders actually spin two kinds of webs: sticky and nonsticky. The sticky web has an adhesive used to trap insects, the nonsticky web has no adhesive and is used for structural supports and traveling by "wind ballooning".

It means there is probably a spider on you. And some sticky web remnants.
