Background
The fact that monarch butterflies are cold-blooded affects every aspect of their lives. A monarch's ability to move, the rate at which it develops from egg to adult, its ability to survive the winter in Mexico without food—are all ways the temperature of a monarch's environment regulates its life.

Children studying monarch butterflies will have questions related to body temperature, thermoregulation and metabolism. Use these resources and activities to explore and build understanding. Discussion Questions are provided to support learning.
