The lateral aspects of larval cephalic cuticle of oak tasar moth, Antheraea proylei, a hybrid between Antheraea pernyi and Antheraea roylei exhibited the presence of gravity receptors in the form of dorsal campaniform sensilla. The distribution pattern and number of dome shaped dorsal campaniform sensilla were found to vary in different larval stages. In the first and second larval stages, 4-5 sensilla were localized near the apex of the lateral aspects of the cephalic cuticle on either side of the head. From the third larval stage onwards, on the other hand, both the right and left lateral aspects of the cephalic cuticle were covered with innumerable dome shaped dorsal campaniform sensilla. The sensilla were found to be arranged in groups of 3 to 5 on the cephalic cuticle with dome-free cuticular portion of about 50-100 µm in length between two adjacent groups of the sensilla. The individual dome shaped dorsal campaniform sensillum was either smooth surfaced or was covered with smaller domes through out the surface. The significance of differences in the number and distribution pattern of the dorsal campaniform sensilla among different larval stages in relation to gravity reception and preferred feeding posture are discussed in the light of available literature.
柞蚕蛾（Antheraea proylei）是柞蚕（Antheraea pernyi）和樗蚕（Antheraea roylei）的杂交种，其幼虫头部角质层的侧面呈现出以背钟形感器形式存在的重力感受器。发现圆顶形背钟形感器的分布模式和数量在不同幼虫阶段有所不同。在第一和第二幼虫阶段，4 - 5个感器位于头部两侧头部角质层侧面顶端附近。另一方面，从第三幼虫阶段开始，头部角质层的左右两侧都覆盖着无数圆顶形背钟形感器。这些感器在头部角质层上以3至5个为一组排列，相邻两组感器之间无圆顶的角质层部分长度约为50 - 100微米。单个圆顶形背钟形感器表面要么光滑，要么整个表面覆盖着较小的圆顶。根据现有文献讨论了不同幼虫阶段背钟形感器数量和分布模式差异与重力感受和偏好取食姿势的关系。
