The numbers 13 and 17 are also prime numbers, and so-called “periodical” cicadas have life cycles of exactly 13 or 17 years. This year, trillions of those creatures are emerging in various U.S ...

North American cicadas have life cycles that last for prime numbers of years. Why 13 or 17 years? Why not 12, 14, 15 or 16? One explanation asks us to imagine the cicadas are hunted by periodical ...

This spring, Brood XIV (as in 14) cicadas will emerge in numbers around the lower billions in 13 states, including Ohio, Gene Kritsky, a biology professor at Mount Saint Joseph University ...

Remember the cicada emergence of 2021? Well, some areas in southeastern Ohio will experience another emergence this spring.

The other way cicadas use numbers, or math, is in their cycles. They stay underground either 13 or 17 years, both prime numbers. Those big and odd numbers are likely an evolutionary trick to keep ...

But when can people expect them? This year’s group, Brood XIV, will emerge in numbers in the lower billions this spring, said Gene Kritsky, founder of Cicada Safari, a group that studies ...

This year’s group, Brood XIV, will emerge in numbers in the lower billions this spring, said Gene Kritsky, founder of Cicada Safari, a group that studies cicadas and gathers data as community ...
