The adult beetle can be seen from April to July, especially in late spring and early summer. In June they can be encountered in a particularly large number. Adults live for up to 8 weeks
Females lay 15-25 eggs in the ground at a depth of 10–15 cm. After a period of 4–6 weeks they hatch and larvae grow up to 2 cm in length and develop in the soil. Larvae take 2–3 years to develop. They overwinter in the ground. In April, they migrate to deeper soil layers to turn into a chrysalis and hatch as an imago, allowing an adult insect to emerge. The males swarm first; the females follow with a few days delay. The females are mated very quickly by flying around males.
