Each year, as the weather gets colder, monarch butterflies make a mass migration to their winter homes. For them, this trip means life or death. As the air cools, butterflies have a hard time flying. Below 55 degrees farenheit, their wings stiffen making it harder for them to fly long distances. Below 40, their wings paralyze completely. Meanwhile, the cooler temperature means the nectar they feed off of is harder to find. They must head south in order to survive. This level 3 reader follows their perilous, but amazing journey, in a fun and informative fashion.
