They're coming. And soon. Millions of Brood X cicadas are likely to begin emerging across central Indiana within the week, according to experts.
Cicadas emerge when the soil temperature reaches 64 degrees, and often after a warm rain, according to John Cooley, an ecology and evolutionary biology professor at University of Connecticut who studies cicadas. With recent warmer temperatures and spring showers across the middle of the state at the beginning of the week, it's likely their debut is just around the corner.
Keith Clay would agree, adding that he thinks the emergence could "take off" by Friday.
"I would say they are not here yet in a major way," said Clay, a distinguished professor emeritus from Indiana University who studied their last emergence in 2004. "But they are coming."
