The caterpillar of the geometrid moth strikes when special tactile hairs on its body are disturbed and, after capturing its prey, holds the victim so that it cannot escape.
capturing的逻辑主语可能是the caterpillar 或hairs阿。
另外,如果是C,The caterpillar of the geometrid moth which strikes when when special tactile hairs on its body are disturbed 这里的which 是否用错了?是不是要用that,因为是限定性定语从句
