利用形态学观察和高速摄影技术，对长角切角象甲（Tomoceruslongicornis）和装饰双角象甲（Dicyrtomarnata）的跳跃器官进行了分析。这两个物种都有一个点击机制，涉及腹部骨片的变形。形态学和摄影证据支持这一假设，即外翻的弹簧器官涉及一个水弹性机制的基础上血腔加压和张力增加的腹部骨片。计算机模型被用来分析跳跃运动学和能量学。这个模型解释了跳跃过程中观察到的自旋，并显示了身体平面形状（例如圆柱形与球形）和尾部长度如何影响自旋的方向，高度，范围和速率。
An analysis of the mechanism of the jumping organ of the cylindrical springtail Tomocerus longicornis and the globular springtail Dicyrtoma ornata is presented based on morphological examination and high-speed photography. Both species have a click mechanism involving deformation of the abdominal sclerites. Morphological and photographic evidence supports the hypothesis that eversion of the springing organ involves a hydroelastic mechanism based on haemocoel pressurization and increased tension in the abdominal sclerites. A computer model was used to analyse jump kinematics and energetics. This model accounts for the spin observed during jumping and shows how body planform (e.g. cylindrical versus globular) and tail length can influence direction, height, range and rate of spin.
