It is disconcerting to discover a wasp nest outside his house, but perhaps a little less thanks to Mattia Menchetti, a biology student, who realized he could donate colored construction paper to a colony of European wasps.
By gradually providing different shades of paper, wasps have turned their homes into a functional rainbow of different colors. This is not the first time that scientists have encountered insects producing colored matter using artificial dyes. In 2012, residues from an M & M plant caused the production of blue and green honey by local bees, and a similar, though more tragic, incident involving bees and the dye used in maraschino cherries. is produced recently in New York.
