CHRYSALIS – CRISALIDA
When the outer shell of the pupa hardens it is known as a chrysalis (KRIH-sah-lis). The process of changing is known as metamorphosis (meh-tuh-MOR-fuh-sis). It takes approximately 10 days to two weeks before a butterfly emerges. A monarch butterfly goes through four unique stages in its life: egg, larva, pupa and adult butterfly. The caterpillar inside the chrysalis disintegrates into a green liquid which is mysteriously transformed into a monarch butterfly.
The Chrysalis starts off with a beautiful lime green color shell and has a striking band of gold near the top and three gold specks scattered near the bottom. According to Journey North, “The color itself comes from cardenolides in the milkweed that larvae eat.” What purpose the gold markings have is still unknown.
