Curious Tiger asks, “Why do spiders make webs?”
Good question, Curious Tiger! Spiders create webs out of silk for many reasons. The two main reasons are for catching food and protecting themselves. A spider’s web can serve as a net, catching insects that fly by. Once caught on the net, the spider can eat that flying insect. This way, the spider doesn’t have to chase after its food! Webs will also move when something larger than the spider moves near by. Based on the movement of their web, a spider can sense an enemy nearby and hide from it.
