Hepialus moths reproduce and lay eggs in the soil, which then become larvae. Cordyceps fungus will invade the larvae, absorb its nutrients, and continue to multiply, causing the larvae to be filled with hyphae and die.
This is the “winter worm”. In the summer of the following year, the Cordyceps fungus grows into a purple-red grass with a height of 4 to 10 cm on the head of the larva.
“Summer grass” emerges from the ground, is excavated and dried, and it becomes what you commonly see. It is mainly produced in the alpine regions and snow-capped grasslands of Qinghai, Tibet, Sichuan, Yunnan, Gansu, Guizhou and other provinces and autonomous regions.
