In early April of the following year, eclosion begins, followed by mating and egg laying; the egg stage lasts 15 days, and the larval stage about 25 days. In early May, the larvae begin to enter the soil to pupate; the pupal stage lasts about 10 days, after which the first-generation adults emerge, with an adult lifespan of about 5 days.
