Cordyceps sinensis is a facultative saprophytic fungus, which hosts Lepidoptera and Batmoth larvae. In summer, bat moths lay their eggs on the leaves of grass and fall to the ground with the leaves. In a month or so, they hatch into larvae and then drill into the wet and soft soil. There is an ascospore of Cordyceps sinensis in the soil layer, which only attacks those obese and well-developed larvae. After being attacked by spores, the larvae burrow into the shallow layer of the ground. Spores grow in the larvae, and the internal organs of the larvae slowly disappear, becoming a body covered with hyphae and buried in the soil. After a winter, when the next spring came, the mycelium began to grow in a warm and humid environment, and it grew out of the ground in summer. The head of an insect grows into a stalk-shaped brown fruiting body, which is shaped like grass. In this way, the body of the larva and the grass together form a complete "Cordyceps sinensis".

ecological distribution

Ecological environment: it is born on larvae such as Cordyceps sinensis and bat moth. It is common in mountainous areas above 4000 meters above sea level, especially in alpine meadows with snow and good drainage.

Distribution of resources: Gansu, Qinghai, Hubei, Sichuan, Yunnan and Tibet.

Because the bat moth grows in the plateau and high mountain area with fish above 4000 meters, and Tibet just meets the conditions.
