Paper Walls

   White-faced hornets build nests out of paper. They make it by scraping wood and mixing it with saliva before forming it into rooms and chambers. The nest grows larger throughout the summer, eventually getting about as large as a basketball. When winter arrives, there are many layers of paper making up the nest, and a layer of air in between the paper. This provides excellent insulation. The hibernating hornets vibrate their wings periodically, giving off body heat that keeps the nest just warm enough for the queen to survive and start another nest in the spring.
