Females are usually larger than males. Males often leave their webs at mating time and these males may wander into our homes. Females either lay eggs in the web or carry them in a sac on their bodies. Most spiders live 1 or 2 years. While developing into adults, spiders molt from 4 to 12 times.
Spiders can overwinter in any stage of their development.
The most recognized special skill of the spider is its ability to make a web. This is done by silk-spinning glands that are on the tip of its abdomen. The silk hardens on contact with the air. Spiders make silk webs as snares to catch prey and to hold egg sacs. They also use silk lines to travel long distances through the air.
