Broods of Cicadas May Become Zombie-like After Emerging
Alexis Thornton
7 months agoStarting in mid-May 2024, two different broods of cicadas will begin emerging. The two broods have not appeared at the same time since 1803.
The ground temperature, about 8 inches deep, must reach about 64 degrees before the insects emerge. Brood XIX emerges once every 13 years, and they will live in 14 states across the Southeast and Midwest.
Meanwhile, Brood XIII only appears once every 17 years and lives in the Midwest. The two broods may overlap in Iowa and Illinois.
In addition to it being highly unusual for the two broods to emerge simultaneously, the cicadas may become affected by a fungus spore called Massospora cicadina.
