The reproductive cycle of the cockchafer is lengthy and triggered by a combination of hormones and environment. Environmental factors, such as the time of day and season trigger endocrines in females. Females in turn send out powerful pheromones, which males detect with their large antennae. Mating occurs typically in late May and early June. Females deposit eggs in a path opposite to that of the pre-mating flight.
After copulation, eggs are deposited about 20 at a time in soft soil.
Average age at sexual or reproductive maturity (male): 3 years.
Key Reproductive Features: iteroparous ; seasonal breeding ; sexual ; fertilization (Internal ); oviparous
