Watch a Webmaster at Work!

          ​This summer, you may be able to observe an amazing event in nature. You can watch a small animal build a structure much bigger than itself, using materials from inside its own body!

          This is what happens when a spider spins a web. Inside a spider are glands that can produce seven different kinds of silk. The silk comes out of little spigots, called spinnerets, at the rear of the spider's body.

          A strand of spider silk is stronger than a similar strand of steel, and spiders use this amazing material in many ways. If they catch an insect, they may wrap it in silk, to eat later. Female spiders enclose their eggs in a silken sac to protect them. And some spiders—almost always females—make webs that are death traps for insects.

          Webs can be in the shape of funnels, sheets, or domes, but the best-known are called orb webs. From an orb web's center, lines of silk radiate out in all directions, like the spokes of a bicycle wheel. After building this basic structure, a spider goes round and round, laying down ever-bigger circles of silk. Some of the silk threads have sticky glue to catch a moth or other prey. A spider can create this whole complex design in an hour or less.

          When an orb web is complete, some kinds of spiders wait right in the center. Others hide at an edge. Either way, the builder keeps a front leg in touch with the web. Vibrations from the threads tell a spider whether prey has been caught.

          Spiders often have to repair their webs, and some species routinely build a new one every day. And they recycle! They eat most of their old web. After digestion, it becomes brand new silk for the next construction job.

          You may be able to watch a spider on the job. Look for webs in a field, park, or backyard. Also look for webs near doors, windows, or on a porch. The nighttime lights from such places attract night-flying insects, and spiders often build webs there. They may or may not be orb webs, but watching any kind of spider at work on its silken insect-trap can be fascinating fun. 

          And remember: the spider wants nothing to do with you. It is just trying to stay safe and catch some food.
