What’s smaller than a hamster and hibernates? The answer may surprise you.
Hibernation usually conjures up the image of a burly bear snoozing in his den, but the truth is, at least two species of butterflies hibernate (sleep through the winter) in their delicate and fragile adult phase—the Mourning Cloak and the Zephyr.
This week, just two days before Easter, I was doubly blessed to see both of these butterflies as they rose from their winter slumber.
How do these ephemeral creatures survive negative temperatures and live to fly again?
