Suppose the cicadas come out every C years and a predator comes out every P years. Then the life cycles of the predator and the cicadas will coincide every LCM(C, P) years. The predator will want it to happen as often as possible while the cicadas want that to happen as seldom as possible. If C is co-prime with P then the cycles coincide after CP years - which is best for the cicada.Suppose the cicadas come out every C years and a predator comes out every P years.

Cicadas typically emerge every 13 to 17 years, depending on the species. The next major emergence of periodical cicadas in the United States is expected to occur in 2024, specifically for Brood XIII, which is a 17-year brood. However, annual cicadas can appear every summer, as their life cycle is not tied to the longer cycles of periodical cicadas.
They are called cicadas (seh-cay-da) and they lay eggs in the ground and the larvae come out every 7 years.
A group of cicadas is called a "brood." Cicadas are known for their synchronized emergence in large numbers, typically every 13 or 17 years depending on the species. These periodic mass emergences are a survival strategy that overwhelms predators and increases the chances of successful mating for the cicadas.

Cicadas typically emerge in late spring or early summer, depending on the species and regional climate. The most well-known periodical cicadas, such as those from Brood X, emerge every 13 or 17 years in large numbers. After their emergence, they mate, lay eggs, and die, with their life cycle continuing underground until the next emergence. Annual cicadas, on the other hand, can emerge every year in warmer climates.
Cicadas do.
Every four years.
Halleys comet comes back around every 76 years.
Brood 2 cicadas do not get eaten underground. They stay underground for many years and then come up through the ground. The can and do get eaten once they emerge. Animals and birds will eat them.
