How Do Spiders Make Webs?

Spiders make webs for many purposes, but they most commonly use them to catch prey. They construct massive webs, which allow them to trap and divide up food. Some of them also weave nets under their bodies or create funnel-shaped burrows.

Most spiders start their web by throwing a single thread into the air. The spider then spins it into concentric circles. This process takes about 30 minutes.

Once the first thread is strong enough, the spider secures the other end of the web. Its legs sway back and forth to add more silk. These sticky strands immobilize the prey.

During the process, the spider senses vibrations through the thread. This alerts the spider to predators. Ultimately, it decides whether to keep controlling the victim or to let go.

Unlike other insects, spiders have the ability to stick to their webs. Using the glue-like substance found in their silk glands, they make a sticky strand that captures the prey.

To build their webs, spiders have special organs on their abdomens. These organs are used to produce different types of silk. Depending on the spider, they may produce smooth or wet silk.

Upon making a web, the spider chooses a location to make it. Often, they build webs around outside lights. They can also make webs in damp, dark places. For example, they will build a web in a leaf.

Usually, the spider chooses a spot with good light and wind. It also uses the location to assess its surroundings. If a predator is nearby, the spider will use the vibrations of the thread to alert it.
