The Oriental hornet has a unique ability to harvest solar energy, scientists have discovered. The large wasp species has a special structure in its abdomen that traps the sun's rays, and a special pigment that harvests the energy they contain. The discovery helps explain why these hornets have a large yellow stripe across their body and why they become more active as the day gets hotter. It also changes our understanding of how insect...
