这种世界上最小的苍蝇叫做Euryplatea nanaknihali


Euryplatea nanaknihali只有盐粒大小,体型比普通家蝇要小15倍

  据《每日邮报》7月3日报道,研究人员日前在泰国发现世界上最小的苍蝇,这种苍蝇通体只有0.4毫米长,大小同人们日常食用的细盐粒相当,甚至比之更小。它们常常寄生在蚂蚁的脑袋内部,长到一定程度后再将寄主“斩首”。

  这种叫做Euryplatea nanaknihali的极小苍蝇是蚤蝇(Phoridae)的一种,体型比普通家蝇要小15倍,比普通果蝇小5倍。

  蚤蝇以斩杀蚂蚁著称,这种蝇科昆虫将卵产在蚂蚁体内,当卵变成幼虫之后,便以蚂蚁的脑袋为食,直到最后使蚂蚁的头颅落地。

  这一发现证明即使是世界上最小的昆虫也可能成为寄生虫的猎物,研究人员称,Euryplatea nanaknihali能将头部仅有0.5毫米大的蚂蚁“斩首”。(苏然)
