Wild insects mushroom grows on the surface of the earth. In the early autumn, when sphingidae and notodontidae (belong to the leaf-eating insects) in the forest turn to the mature time, they climb down from the trees to the earth. When they enter down to the surface 2 to 3 cm, sphingidae and notodontidae spin cocoons and then pupate. Affected by the wind, the rain and other insects, the spores spread to the polypide or the pupa, which makes it stiff gradually. Next summer, when there are abandant rainfall, humidity, high temperature, the orange carpophore grows from the polypide or the pupa, about 2 to 4cm long, they are so called Cordyceps Militaris.
