Atlas moths are considered the largest moths in the world. Their wing span can reach 12 inches with a surface area of 62 square inches.They are said to be named after the Titan of Greek Mythology. Despite their large size, they have no mouths and don’t eat once emerging from their cocoons, relying on fat storage from their immature stages of life. After spending about a month in their cocoons, Atlas Moths emerge as the beautiful creatures. Unfortunately, this state is short lived as the adult moths typically die within a week or two of spreading their wings. They are truly an amazing creature but unfortunately their beauty is short lived.
