The life-cycle of Callibia diana Stål is described and linear and geometric morphometrics are used for studying allometrics and shape changes throughout this neotropical mantid species' life-cycle. Significant changes were expected in the allometry and shape of the raptorial leg and abdomen, given the importance of hunting and reproduction. The allometric slopes were obtained by using total length as the independent variable. Geometric morphometrics of landmarks were used for frontal femur and tibia. Hunting and reproduction-related structures had the steepest slopes and positive allometries. Negative growth of both disc width and head width found in the last moulting event may be a consequence of prothoracic muscle growth which is responsible for predatory strike strength. The tibial claw and femur of the raptorial leg become larger, while their spines become more orthogonal to the longitudinal axes which may facilitate prey retention. These changes in mantid shape throughout ontogeny were consistent and suggested the resource allocation and development programming of the body that improved reaching distance and prey retention.
本文描述了戴安娜螳螂（Callibia diana Stål）的生命周期，并运用线性和几何形态测量学方法，研究了这种新热带区螳螂物种在整个生命周期中的异速生长和形态变化。鉴于捕猎和繁殖的重要性，预计捕捉足和腹部的异速生长及形态会发生显著变化。通过将总长度作为自变量来获取异速生长斜率。地标点的几何形态测量学应用于前足股骨和胫骨。与捕猎和繁殖相关的结构具有最陡的斜率和正异速生长。在最后一次蜕皮事件中发现的翅宽和头宽的负增长，可能是负责捕食攻击强度的前胸肌肉生长的结果。捕捉足的胫爪和股骨变大，而其刺变得更垂直于纵轴，这可能有助于捕获猎物。螳螂在个体发育过程中的这些形态变化是一致的，表明身体的资源分配和发育程序得到改善，从而增加了捕食范围和猎物捕获能力。
