"Unprecedented 2024 Cicada Emergence: A Once-in-221-Years Event"

For the first time in 221 years, two broods of cicadas, Brood XIX and Brood XIII, are expected to emerge simultaneously across 17 states in North America in spring 2024, creating a "simultaneous explosion" of the insects. This unique event will overlap in areas across Indiana and Illinois and is anticipated to be quite noisy, reaching 105 decibels. While some may dread the emergence, cicadas are largely harmless to humans and animals, although their exoskeleton material may upset the stomachs of some animals.
