Eggs

Female orb-weavers produce around 2,500 eggs in a sac, made of silk.

Spiderlings

Spiderlings go through molting before their hatching. They chew off the sac and make the way clear for easy hatching. Spiderlings from one clutch often build small webs and live together for a short period to protect themselves from predators. Then, after reaching adulthood, they spin a soft strand of silk and let the wind blow the silk away, including them. This is known as the process of ballooning.

The Web
