Spider webs are amazing.CHANGING FOR THE CONDITIONSA spider’s silk-making organ has hundreds of small openings. Silk comes out of these air, it becomes thread-like. These tiny threads combine to form a single, solid thread.The spider can make many different kinds of thread. The threads can be thick or thin, wet or dry, sticky or woolly. Each kind has a different purpose. Some webs create an egg case. Others provide hiding places. The most common purpose of a spider web, however, is to catch food.TRICKS FOR CATCHING DINNERThere are many ways the spider uses its web to catch prey. For example, some spiders spin a single thread. An insect then sits on it without realizing what it is doing, and becomes stuck. Slowly, the spider moves toward the insect. Suddenly, it covers its prey in silk.Argiope spiders use a different kind of trap. They make webs that confuse insects. An insect sees the web and thinks it’s a flower. It then lands on the web. The spider can feel even the smallest movement of the web, and rushes at the insect before it can get away.Spider webs are so amazing that engineers have been studying them for years.
