While some insects, like moths, spin a cocoon, a butterfly uses a chrysalis, which is essentially hardened skin. Different species of butterflies stay in the chrysalis, or pupal stage, for different periods of time. This can range from about seven days to more than a year, but for a large number of species it is less than 30 days. The well-known monarch butterfly, for example, spends between nine and 14 days in a chrysalis, while the painted lady butterfly spends only seven to 10 days in the chrysalis.

Popular sovereignty is the principle that the ultimate authority of  a society is the people, and the government's power rests entirely  on the consent of the governed. The â¦ framers of the Constitution  emphasized this by prefacing it with We the People. Kathleen Hughes.
