CONVERGING CICADAS
05/03/2024 |
The Fun Finale: Sometime in May, when the soil temperature eight inches deep reaches 65 degrees, trillions of cicadas will emerge, mate, lay eggs and then die, all in about five weeks. What makes this year special is that Brood XIII, which has a 17-year cycle and Brood XIX, with a 13-year cycle (all broods have prime-numbered cycles), will emerge simultaneously. The last time this happened was 1803.
