时差N小时 昆虫的世界(上)（在线收听）

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

你曾走进过昆虫的世界吗？——飞虫，蚊子，或他们的表兄弟——然后发现自己无法撼动这群昆虫？你假装离开，向右走，但小昆虫们仍然徘徊在上面。看还来这还不够糟糕，你知道你头上所发生的场景吗？那已经成为小飞虫想前往的地方。换句话说，昆虫群相当于一个单身盘对酒吧？说对了，昆虫群正是雌、雄昆虫相见和问候的地方。昆虫学家首次报道了昆虫聚集成群的目的是在1906年。Frederick Knab写道，他从飞虫群中捕捉了901只蚊子，但只有4只是雌性的！
