In the spring time (warm seasons) the female rhinocerous beetle lays around 5o white eggs in the soil.
In about a month the eggs will hatch, they enter the larval stage in life. The larva live underground from 6 months to a year. In this process they grow and molt twice before they enter the next stage.
Pupa and Adult:
The pupa stage isn't very long, it usually occurs in a few weeks. Once they have reached the adult stage, they remain underground until springtime. During the spring, the female releases phermones to attract the males as they surface. After they mate, the female digs into the soil and lays the eggs, thus repeating the cycle.
