Pere Renom

“We gave you no fixed place, no form of your own, nor any assigned task, O Adam, so that by your own choice you might possess the place, the image, and the role you desire; neither heavenly nor earthly, neither mortal nor immortal did we make you, but free to shape yourself in the form you prefer, as your own maker and sculptor.”

Giovanni Pico della Mirandola

Yellow and black wasps and red and black heteroptera are aposematic insects, dangerous due to their bites or their venom. Humans use aposematism in the design of the war shields of several African tribes, in the military clothing of the eighteenth century, or in the flags of the countries. And a beautiful example is found in Barcelona’s taxis. The combination of yellow and black is obviously not a warning sign, but it stands out in the middle of traffic and facilitates the location of vehicles.
