点击甲虫（鞘翅目：Elateridae）以其独特的点击机制而闻名，可以产生强大的无腿跳跃。从倒立位置开始，点击甲虫通过快速向上加速其质心 (COM) 来跳跃。先前对点击甲虫跳跃的研究主要集中在相对较小的物种（体长范围为 7 至 24 毫米），并假设 COM 在空中阶段遵循弹道轨迹。在这项研究中，我们记录了来自不同点击甲虫属的 38 个标本（体长从 7 毫米到 37 毫米不等）的跳跃和形态，以研究体长和跳跃性能如何在整个质量范围内变化。实验结果用于检验弹道运动假设。我们推导了点击甲虫的第一个形态测量缩放定律，并提供了点击甲虫身体随着体重增加而等距缩放的证据。开发线性和非线性统计模型来研究跳跃运动学。建模结果表明，质量并不能预测跳跃高度、起飞角度、起飞速度和最大加速度。弹道运动假设得到强烈支持。这项工作提供了一个建模框架来重建完整的形态数据集并预测各种形状和大小的点击甲虫的跳跃性能。
Click beetles (Coleoptera: Elateridae) are known for their unique clicking mechanism that generates a powerful legless jump. From an inverted position, click beetles jump by rapidly accelerating their center of mass (COM) upwards. Prior studies on the click beetle jump have focused on relatively small species (body length ranging from 7 to 24 mm) and have assumed that the COM follows a ballistics trajectory during the airborne phase. In this study, we record the jump and the morphology of 38 specimens from diverse click beetle genera (body length varying from 7 to 37 mm) to investigate how body length and jumping performance scale across the mass range. The experimental results are used to test the ballistics motion assumption. We derive the first morphometric scaling laws for click beetles and provide evidence that the click beetle body scales isometrically with increasing body mass. Linear and nonlinear statistical models are developed to study the jumping kinematics. Modeling results show that mass is not a predictor of jump height, take-off angle, velocity at take-off, and maximum acceleration. The ballistics motion assumption is strongly supported. This work provides a modeling framework to reconstruct complete morphological data sets and predict the jumping performance of click beetles from various shapes and sizes.
