The life span of the adults typically ranges from 10 to 20 days. The larvae begin to target roots shortly after emerging. They create burrows and channels within the roots as they consume plant material, progressing upward and inward, frequently causing death to the apical areas. As the larvae mature and increase in size, they migrate from thinner to thicker roots, ultimately reaching the root crown. Pupation takes place close to the ground surface in a chamber made of soil and root debris. There is typically one generation every two to four years.
