In an interesting experiment, biology student Mattia Menchetti—who is currently pursuing his Masters in Science at the University of Florence—left a stack of colored construction paper for a group of European Paper Wasps and photographed the resulting nest they created.
Menchetti posted the series of close-up photos on his blog, Notula Zoologica, and the rainbow-colored results are quite fascinating.
