But adult planthoppers can jump at more than 12 miles an hour.

但是成年的稻飞虱每小时跳行12英里。

Froghoppers, and their cousins planthoppers and leafhoppers, do this using an incredibly cool simple machine that is built in their bodies.

沫蝉，以及它们的表亲飞虱和叶蝉，使用一种非常酷的简单机器来做到这一点，这种机器是在它们的身体里建造的。

A new study reports that the planthopper Issus coleoptratus evolved a foolproof solution to this problem: in young nymphs of the species, the two legs meet under the belly in plates fringed with interlocking teeth.

它们在幼年时期，它们的两条腿在肚子下方被有紧连着的牙齿的鳞甲连接。
