From The Mother Spider To The Spiderlings In The Egg Sac

 

  • Many spiders die in the fall after producing an egg sac, but some live through the winter and mate in the spring then die. Others survive for two or more years, including the wolf spider that may live for several years and the tarantula that has been known to live for 20 years.
  • The average female spider’s egg sac holds about 100 eggs, but larger spiders can produce as many as 2,000!
  • The egg sac is either attached to a web, plant or other structure, and some mothers protect the sac till the spiderlings emerge. Other spiders will carry the sac on their abdomen and some drag it behind them.
  • Most baby spiders hatch when the weather gets warm, but still stay quietly inside their egg sac until spring.
  • When the spiderlings first emerge from the sac, they spin a dragline and balloon away.
