Answer: Mrs. Nunnally's second grade class at Peter Woodbury School in Bedford NH thinks nectar is so important during the fall migration because if they don't have nectar they will die, butterflies need food just like we need food; if the butterflies don't store fat, they can't last the entire winter; when they migrate they need energy that they get from nectar.

Monarchs need to hurry because if they waste their time, the flowers will die and they won't have food. Also if they stay in the north, it will become too cold with too much snow and they will die. The butterflies need to hurry south because they need nectar and sunlight.
