The next stage of a monarch's life is called the Pupa
or a
chrysalis. This stage can last up to two weeks as the chrysalis changes from a light green to
a darker black and orange. When the adult butterfly is ready to emerge, it will
eclose
out of the chrysalis. It will then hang from the shell of the chrysalis while
its wings inflate and it prepares to take its first flight. As an adult butterfly, it will only get its
energy from
from flowers. You can tell an adult male from a female
nectar
hind
because the male will have two black spots on the hind

have. Instead of eating and growing like a caterpillar, as an adult, the monarch's job is to
mate and lay eggs.
Milkweed is an herbaceous plant that is completely necessary for monarch's survival. It is a
plant, which means it grows back from its roots every year. It is
considered a weed by most gardeners and farmers, so it is often killed with pesticides and
herbicides. Milkweed is
to other animals because it contains a toxins
called cardiac glycosides in its sap. Caterpillars store the poison in their bodies until they
become butterflies, so when predators try to get them, they get poisoned.
