Insects, on the other hand, have six legs and three body regions. Spiders live almost everywhere, including inside homes and buildings. Spiders feed entirely upon living insects or animals small enough for them to catch. They usually lie in wait for their prey, and many build webs to trap them. The silk is secreted in liquid form, which hard-ens when exposed to the air.
Spiders reproduce by laying eggs contained in an egg sac.
These sacs are usually ball-shaped and may be carried by the female wherever she goes. Some species hide their sacs in the web or tuck them away elsewhere. Egg sacs frequently contain several hundred eggs. Some people have the idea that all spiders are poisonous or dangerous to handle, but this is not true. The Brown Recluse or Black Widow will not bite unless provoked.
