And unlike their open-air cousins, London’s subterranean skeeters seemed to love biting humans.
Fifty years after the war ended, scientists at the University of London decided to investigate the subway population. They collected eggs and larvae from subway tunnels and garden ponds and reared both populations in the lab. The tunnel bugs, they confirmed, preferred feeding on mammals over birds. And when the scientists put males and females from different populations in close quarters designed to encourage mating, not a single pairing produced offspring. That sealed the deal: The underground mosquitoes were a whole new species, adapted to life in the subway tunnels people had built.
