Scientific analysis:
The mycelium of Cordyceps militaris is a ascomycete, and its asexual form is Penicillium chrysalis. Ascomycetes (reproductive units) can be formed after bacteria mature. After the spores dispersed, they spread with the wind, landed on suitable insects, and began to germinate, forming mycelium.
While the mycelium is developing, it begins to spread into the worm, so the pupa will be infected by fungi, decompose the tissues in the pupa, take the nutrition in the pupa as the material and energy source for its growth and development, and finally completely decompose the pupa.
