Billions of cicadas from two broods are expected to emerge in 17 U.S. states in April in an event not seen since 1803. Brood XIX and XIII cicadas emerge every 13 and 17 years respectively from underground, where they develop.
Million cicadas

If the estimated population of a million cicadas per acre is accepted, the total combined area of the periodical cicada emergence is projected to involve more than a trillion cicadas. This astronomical number underscores the sheer magnitude of this natural spectacle, offering a rare opportunity to witness the remarkable phenomenon of mass cicada emergences.

The upcoming emergence of trillions of periodical cicadas in the Eastern United States in 2024 is set to be an extraordinary and rare occurrence, captivating the attention of entomologists, the general public, and researchers alike. This unique event is poised to offer a mesmerizing display of nature’s wonders, shedding light on the complex life cycles and ecological significance of these intriguing insects.
Once-in-a-generation

The convergence of the 13-year and 17-year cicada broods in 2024 is a once-in-a-generation event, occurring only once every 221 years. This exceptional synchrony is expected to result in the emergence of trillions of adult cicadas across an expansive area spanning from Maryland to Oklahoma, Illinois to Alabama, encompassing approximately 1.5 million acres.
Prime numbers

“The co-emergence of any two broods of different cycles is rare, because the cycles are both prime numbers,” UConn cicada expert John Cooley said.
13 and 17-year

“Any given 13 and 17-year broods will only co-emerge once every 13 x 17 = 221 years.” Their simultaneous emergence occurs once every 221 years.
1-2 inch

The 1-2 inch bugs will engage in mating before females lay eggs in tree branches and all eventually die. While their loud noises can be bothersome, cicadas are harmless to humans, pets and most plants.
Provide food

They provide food for other animals and aerate soil. Their emergence overlaps in a small area of Illinois and Indiana. “This summer, some will get a chance to witness a phenomenon rarer — and probably louder — than Halley’s comet,” Cooley said.
Millions and millions

“You cannot possibly be unaware that periodical cicadas are out, because they’re out by the millions and millions, and they’re noisy, charismatic, active insects that are just everywhere,” Cooley said. Young trees may be covered to prevent egg-laying from harming them.
Climate change

The impending emergence of trillions of cicadas raises questions about the potential impact of climate change on their life cycles and geographic distribution. While it is acknowledged that cicadas have historically been affected by climate change, the specific implications for the 2024 emergence remain complex and multifaceted.
Ecosystems

The emergence of such vast numbers of periodical cicadas presents an opportunity to explore the intricate interplay between these insects and their surrounding ecosystems. The ecological significance of cicadas, including their interactions with plant life and other organisms, underscores the enduring importance of understanding their role in shaping local biodiversity.
Future research

The theoretical prospect of hybridization between co-emerging 13-year and 17-year cicada broods has sparked scientific inquiry into the potential outcomes of such events. The genetic and life cycle implications of interbreeding between different periodical cicada broods offer a compelling avenue for future research and scientific exploration.
