Environmentally, spiders are very important pests. They are predators that feed on a wide variety of garden and other nuisance pests, helping to keep their populations from overtaking an area. These eight-legged creatures are part of the class Arachnida. Spiders have only two body regions (head and abdomen), unlike insects that have three. They lack wings and antennae but have fangs that they use to inject venom into their prey. Spiders also have spinnerets at the end of their abdomen they use to produce silk, although not all spiders use it build webs. This silk is used to climb, line their burrows, wrap up their prey, and even as a lifeline to help spiders find their way back to their webs or burrows. Under the right environmental conditions, spider silk is stronger than steel!
