• The chrysalis is not a cocoon. A moth forms a cocoon. A butterfly forms a chrysalis.

• The chrysalis is also called the pupa. The process of changing from larva to chrysalis is pupation.

• The green coloring of the monarch pupa is the skin of the monarch during this life stage.

• The final molt (shedding skin) of the monarch larva results in the chrysalis. "The chrysalis is not so much something the monarch makes as something it turns into," says Dr. Oberhauser.
