A web that is seen often is an orb spider web. These webs are found in fields, woods, cities, and gardens. Orb spiders spin webs to catch insects.

First, the spider lets out a long strand of silk. The silk floats in the breeze. The spider waits for it to catch on a branch. Second, the spider attaches silk to the ends of the first line and drops off of it. The silk makes a triangle shaped web. Third, the spider makes the outside edges of the web. The web can have many sides.

Fourth, the spider makes many lines of silk from the middle of the web out to the edges. The web looks like a pizza cut into many thin slices. Fifth, the spider goes to the middle of the web. The spider starts to add silk lines in a spiral out to the edge of the web. Sixth, the spider adds another spiral over the first one. It is made of sticky silk. This silk will catch insects.

Some orb spiders sit in the middle of the web and wait for an insect to get caught. Other orb spiders make a long line of silk from the web to a hiding place. It waits to feel an insect in the web.

These webs take one hour to make. They are usually gone in a day. Some spiders leave their webs to go make a new one. Some spiders eat their own webs.
