Will silkworm cocoons and pupae live under the big tree in spring?

Cicadas spend the first two or three years of their lives underground, maybe longer. In the meantime, it sucks liquid from the roots. Then one day, I broke out of the ground and found a tree to climb with my instinct to survive. After several years of slow growth, cicada pupa climbed out of the ground as an energy storage body. Its front paws for digging holes can also be used for climbing. It usually takes one to two years from the beginning of the egg to the nymph living underground, until it finally emerges as an adult and blooms in the tree.

Spring, also known as spring, is the first of the four seasons, which refers to the period from beginning of spring to long summer, including solar terms such as beginning of spring, rain, fright, vernal equinox, Qingming and Grain Rain. This is the season when everything comes back to life. The Gregorian calendar in the northern hemisphere is from early February to early May, and in the southern hemisphere (such as Australia) it is from September to 165438+ 10. In meteorology, the beginning of spring is that the average temperature is above 10℃ for five consecutive days. In spring, the climate is warm and mild, and there is rain in most inland areas of China, where everything germinates and the climate is changeable.
