英国广播公司5月29日报道,欧盟科学家最新公布的一份报告称,科研人员刚刚发现一种阿尔卑斯山公蟋蟀可谓十足的"大流氓",做起爱来很疯狂---平均每18秒钟就可以交配一次!
大多数公蟋蟀在交配之前,都要和雌性相互"对唱情歌",吸引雌性。而这种蟋蟀很粗鲁,交配常导致雌性受伤。这种蟋蟀学名称为Anoncontus
alpinus,它常常突然跳到从它边上路过的蟋蟀身上,不论雄雌,强行交配!更有甚者,它在一次交配后只休息几秒钟,就可以再次"开始行动"!
达比大学的昆虫学家瓦赫德和日内瓦大学的一些研究人员在阿尔卑斯山区发现了这种蟋蟀不寻常的交配能力。一般蟋蟀在交配前都会发出声音,如同"对唱情歌"。而雌蟋蟀不喜欢听到"异邦情调"。
瓦赫德说:"这种交配前的对歌防止不同种类的蟋蟀错误的交配。"
而这种阿尔卑斯山蟋蟀完全不顾这些"礼节",不经介绍就乱来,而且不管对方是雄是雌!
瓦赫德和其他研究人员准备花更多的时间,搞清楚这种阿尔卑斯山蟋蟀的物种繁衍情况。他们想知道,两个这种阿尔卑斯山蟋蟀碰到一起会发生什么情形。
