印度蚂蚁Harpegnathos saltator可能是昆虫中唯一的一种，它不仅将跳跃能力用作逃跑机制，而且还将其用作正常的运动手段，并用于捕获飞行中的猎物。用于分析跳跃的各个阶段的高速电影摄影表明，Harpegnathos采用了一种新的跳跃机制来调解这些行为：即其中间和后腿的同步激活。从肌肉或神经对中，后腿的电生理记录显示，在虚构的跳跃过程中显着的同步活动，支持同步激活假说。Harpegnathos并不是唯一一种跳跃的蚂蚁，分支分析表明，在蚂蚁进化史上，跳跃行为独立进化了三次。
The Indian ant Harpegnathos saltator may be unique among insects in using its jumping capacity not only as an escape mechanism but also as a normal means of locomotion, and for catching its prey in flight. High-speed cinematography used to analyse the various phases of the jump suggests that Harpegnathos employs a novel jumping mechanism to mediate these behaviours: namely the synchronous activation of its middle and hindlegs. Electrophysiological recordings from muscles or nerves in pairs of middle and hindlegs show remarkably synchronous activity during fictive jumping, supporting the synchronous activation hypothesis. Harpegnathos is not the only ant to jump, and a cladistic analysis suggests that jumping behaviour evolved independently three times during ant evolutionary history.
