Spiders lay eggs within a silken egg sac that is often ball-shaped and either hidden in the web or carried by the female. Spiders may produce several egg sacs, each containing from 100 to several hundred eggs. One female may produce as many as 3,000 eggs in a series of several sacs over a period of time. Eggs may hatch a few weeks later (three weeks or the following spring) and reach adulthood in one year. For a spider to grow, it must shed its skin (molt) usually four to twelve times before maturity. Most spiders live either one to two seasons. Some spiders may overwinter as eggs, spiderlings in the egg sac, immature spiders living outside the egg sac, or as adults.
