A Sheded Skin of Two Stripe Spider

The process in which a Spider sheds its skin is known as "Moulting"..
Spiders moult their skins as many as 8 times before reaching adulthood. During the moulting process they can lose a leg, which will be regrown at the next moult. When the spider's cuticle is stretched to the limit the spider can grow only by moulting. Spiderlings may moult every few days, and increase in size with each moult. The time between moults increases with age. When a spider is about to moult it will stop eating, and some species seal themselves inside a silk-lined chamber. The new cuticle is soft and pale. The old cuticle or exuvium is often mistaken for a dead spider. The cuticle hardens and takes on normal colouration within a few hours.
