Wasps Built These Colorful Nests with Colored Paper

Mattia Menchetti is a graduate student in biology at the University of Florence in Italy. He specializes in the study of the social wasp (Polistes dominula). This study is not one of merely science, but also art.
Menchetti says that the cellular nests of wasps are natural wonders. All they need to gain human notice is a bit of flair. So he gave captive wasps pieces of colored paper, which the wasps then used to build their nests. You can see more photos here (translation).
