During rainy days, monarch butterflies rarely move. They must wait for their wings to dry before taking flight. Increasing extreme winter storms and drought conditions have contributed to declining monarch populations. Monarchs are capable of withstanding freezing temperatures and some rain but not for long periods of time. Monarchs can fly when temperatures are higher than 60 degrees Fahrenheit, and 50 degrees Fahrenheit when sunny.
