1.  Spider and its Egg Sac:

  • A female spider lays hundreds of eggs. 
  • The spider wraps the eggs in threads of silk to make an egg sac. 
  • Then she hangs the egg sac in her web.

2.  Hatching:

  • The eggs hatch inside the egg sac. 
  • All the baby spiders, called spiderlings, stay inside the sac until the weather is warm.
  • The spiderlings continue to grow in their egg sacs. 
  • They bite a tiny hole in the egg sac and come out when they are ready.

  • They will be eaten by other hungry spiderlings.

4.  Ballooning

  • The spiderling leaves the other in few days.  She goes ballooning to find a new home.  She climbs to the top of something tall, to catch a breeze. 
  • The spiderlings let out silk from their spinnerets.  The breeze tugs at the silk. 
  • The wind lifts and carries all the spiderlings.  They make their home wherever they land.

5.  Moulting

  • Her skin gets tight as the spiderling grows.  It is too small for her now.  She must get rid of her old skin.  She hangs upside down from a silk thread. 
  • Her old, dry skin splits along the sides of her body.  Then she pulls her legs out of the skin.  Getting rid of her old skin like this is called moulting.
