Cicadas are insects that live underground for most of their lives, emerging every 13 or 17 years in massive numbers to molt, mate, and die. This synchronized emergence overwhelms predators, ensuring some cicadas survive to reproduce. Cicadas are known for their loud mating calls, which can reach up to 100 decibels. They face various predators and parasites, including the Massospora fungus. The reason for their specific emergence cycles remains uncertain, though it may relate to prime numbers. After mating, cicadas lay eggs, continuing the cycle for future generations.
