From March to April of each year, large, well-developed, healthy and disease-free male and female adult cicadas are selected and placed into a spawning pond. The pool is filled with a certain depth of water (20-50 cm) and the water temperature is maintained at 25°C. About 3 to 5 pairs per square meter. Males were injected with 300 units of chorionic gonadotropin once daily for two consecutive days. At the same time, females were injected with 600 units of human chorionic gonadotropin. After sexual maturity, males and females usually mating and fertilizing at night and spawn in the water in the morning. Each female can lay about 5,000 eggs. At this time, the eggs are collected and placed in the breeding ground or hatching area. Fertilized eggs usually hatch at 50 °C for 25 hours at 25 °C.

(i) Reproductive characteristics: An important type of vertebrate is the intermediate type of transition from aquatic to terrestrial, male and female adults spawn in water and fertilized in vitro. The fertilized eggs hatch in the water, and they breathe with the earthworms. After about 60 days of metamorphosis, the tail disappears into a beak and begins life on land, breathing with the lungs. At the same time, the skin secreted mucus to help breathing, its internal organs gradually improved, about 16 months into adulthood; sexual maturity. Most of the males and females mating in the spring, usually males embrace the females. When the females ovulate, the males finally finish their fertilization and complete fertilization in vitro to begin the next generation.
