The trunk morphology of the larvae of the kauri pine (Agathis) seed infesting moth Agathiphaga is described using conventional, polarization, and scanning electron microscopy. The pine seed chamber formed by the larva is also described and commented on. The simple larval chaetotaxy includes more of the minute posture sensing setae, proprioceptors, than expected from the lepidopteran larval ground plan. The excess of proprioceptors is suggested to be necessary for sensory input concerning the larval posture within the seed chamber. The trunk musculature includes an autapomorphic radial ventral musculature made up of unique multisegmental muscles. The combined presence of additional proprioceptors and the unique ventral musculature is proposed to be related to the larval movement within the confined space of the seed chamber, especially to a proposed somersault movement that allows the larva to orientate itself within the chamber.
利用传统显微镜、偏光显微镜和扫描电子显微镜描述了侵染贝壳杉（贝壳杉属）种子的蛾类——贝壳杉食叶蛾幼虫的躯干形态。还对幼虫形成的松子腔进行了描述和评论。简单的幼虫刚毛序包括比鳞翅目幼虫基本模式预期更多的微小姿态传感刚毛（本体感受器）。有人认为，多余的本体感受器对于获取种子腔内幼虫姿态的感觉输入是必要的。躯干肌肉组织包括由独特的多节段肌肉组成的自近裔性状放射状腹侧肌肉组织。有人提出，额外本体感受器和独特腹侧肌肉组织的共同存在与幼虫在种子腔有限空间内的移动有关，特别是与一种推测的翻滚运动有关，这种运动使幼虫能够在腔内定向自身。
