Hibernating Butterflies

Adult Mourning Cloaks spend the winter hibernating. It's difficult to think of such a delicate looking creature surviving a winter day like this one with minus zero temperatures and over two feet of snow on the ground.

Mourning Cloaks depend on trees, mostly willows, and survive on tree sap. I found this one fluttering around on the forest floor one June day.
