Cordyceps sinensis is a kind of fungus, which is a special organism born of insects and fungi. The mycelium of Cordyceps sinensis infects the larvae of Hymenoptera (Lepidoptera Hymenoptera, Hymenoptera) in various ways, and takes the organic matter in its body as the source of nutritional energy for parasitic life. After continuous growth, development and differentiation, the mycelium finally kinks and forms a daughter that extends out of the host shell, thus forming a special insect-borne organism.
