Like birds, some wasps build nests with the materials they have at their disposal. That’s why when biology student Mattia Menchetti had the idea to set out construction paper for the European paper wasps outside of his house, they set to work in creating the most colorful hives we’ve ever seen. Menchetti gave the wasps the paper gradually, alternating in color. Over time, the wasps built their incredible, striped homes from the paper, and the resulting hives are absolutely beautiful. Check out some of their colorful creations below.
