Cicada-palooza: A Phenomenon Sweeping America with Billions of Bugs
Cicada-palooza is upon us! This captivating natural event involves billions of cicadas emerging across America, enveloping suburbs and woodlands in their distinctive sounds and presence. This year, two cicada “broods” are set for a rare simultaneous emergence, a phenomenon that last occurred over two centuries ago. Let’s delve into the fascinating world of these insects and explore the significance of Cicada-palooza for both science and the ecosystem.
Cicadas: Mysterious Creatures with a Unique Life Cycle
Cicadas are a diverse family of insects, with over 3,000 species found worldwide. These fascinating bugs spend the majority of their lives underground in a larval state before emerging as adults to mate and transform. While some cicada species appear annually, others, known as periodical cicadas, synchronize their emergence every 13 or 17 years. The mathematical mystery of why periodical cicadas follow prime number cycles has puzzled scientists for years.

The current event involves the 13-year Brood XIX in the Carolinas, followed by the 17-year Brood XIII in the Midwest, with a slight overlap in central Illinois. Entomologist Gene Kritsky highlights the excitement surrounding the harmless red-eyed bugs, noting that cicadas are not only fascinating creatures but also hold historical significance. People often vividly remember previous cicada emergences, with personal stories becoming part of family lore passed down through generations.
The Ecological Impact of Cicada Emergences
While cicadas may seem defenseless individually, their strength lies in their sheer numbers. These insects serve as a vital food source for predators like birds, foxes, and raccoons. Recent research has revealed broader impacts on the ecosystem during cicada emergences. For instance, the 2021 emergence of Brood X in Washington led to a surge in caterpillar populations as insectivorous birds focused on feasting on cicadas. This, in turn, affected the consumption of oak saplings and even influenced the production of acorns.
The cyclical nature of cicada emergences has long-term ecological implications, with mast years following cicada events leading to increased risk of Lyme disease in humans due to larger populations of acorn-eating mammals. John Lill, a biology professor, emphasizes the interconnectedness of these events, underscoring how cicadas play a crucial role in shaping the ecosystem dynamics.
Challenges and Uncertainties Facing Cicadas
Climate change poses a significant challenge to cicadas, as rising temperatures can disrupt their internal clocks and life cycles. As the US warms up, cicadas may experience accelerated growth due to a longer plant growing season. Chris Simon, a researcher at the University of Connecticut, warns that this could lead to genetic assimilation, potentially altering cicada traits in the long run.
The impact of land transformation since the colonial period on cicadas remains unclear. While historic deforestation has led to the loss of some cicada broods, suburban environments with well-lit trees have provided ideal conditions for cicadas to thrive. The intricate life cycle of cicadas—from adults mating and laying eggs to newly hatched nymphs burrowing underground—underscores the resilience of these insects in the face of changing landscapes.
In Conclusion
Cicada-palooza represents a captivating natural spectacle that brings together science, history, and ecology. The emergence of billions of cicadas across America not only offers a unique opportunity for scientific observation but also highlights the intricate connections within ecosystems. As these bugs continue to enchant and intrigue us with their synchronized emergences and deafening mating choruses, they serve as a reminder of the wonders of the natural world and the importance of understanding and preserving biodiversity.

The cicadas () are a superfamily, the Cicadoidea, of insects in the order Hemiptera (true bugs). They are in the suborder Auchenorrhyncha, along with smaller jumping bugs such as leafhoppers and froghoppers. The superfamily is divided into two families, the Tettigarctidae, with two species in Australia, and the Cicadidae, with...

Periodical cicadas
The term periodical cicada is commonly used to refer to any of the seven species of the genus Magicicada of eastern North America, the 13- and 17-year cicadas. They are called periodical because nearly all individuals in a local population are developmentally synchronized and emerge in the same year. Although...

Brood XIX
Brood XIX (also known as The Great Southern Brood) is the largest (most widely distributed) brood of 13-year periodical cicadas, last seen in 2024 across a wide stretch of the southeastern United States. Periodical cicadas (Magicicada spp.) are often referred to as "17-year locusts" because most of the known distinct...
