時差N小時:昆蟲的世界(上)

　　Have you ever walked into a swarm of insects—gnats,mosquitoes, or one of their many cousins–and thenfound yourself unable to shake the swarm? You fakeleft, go right, but the little buggers still hoverabove. As if it that weren’t bad enough, did youknow your head had just become the happeningscene, where every hip gnat wants to be–in otherwords, the insect world’s equivalent of a singles'bar? That’s right, swarms are places for the sexes tomeet and greet. The first time an entomologistreported the purpose of swarms was in 1906.Frederick Knab wrote that he’d netted 901 mosquitoes from a swarm, but only 4 were females!
