In the natural world, there are phenomena that captivate the imagination and evoke a sense of wonder. One such extraordinary event is currently unfolding as billions of cicadas to emerge from the ground for first time in 221 years.
Overwhelmed by this snowfall? Get ready. When summer arrives, we're in for some quite different kind of storms.
Imagine hordes of bloody-eyed cicadas that have fought their way from underground lairs to the surface of the earth. Trillions of these are bolstered bugs. Fortified and resilient from their days as nymphs consuming the fluids from plant roots, their translucent wings will see daylight for the first time.
For around a month later this year, the US states of Wisconsin and Illinois will be the most affected as billions of the bugs, which make a loud clicking noise, flood the air and cover branches, sign posts, and sidewalks.
The simultaneous emergence of Brood X and Brood IX, two distinct groups of cicadas, is capturing the attention of scientists, nature enthusiasts, and curious onlookers alike.
In the realm of insects, few species captivate the imagination and spark fascination quite like cicadas. Known for their distinct buzzing sounds that resonate through summer landscapes, cicadas undergo a remarkable and protracted life cycle, encompassing stages of growth, transformation, and emergence. Understanding the intricacies of the cicada life cycle unveils a story of resilience, adaptation, and the crucial role these insects play in the ecosystems they inhabit.
The journey of a cicada begins with the laying of eggs. Female cicadas deposit their eggs in tree branches, using their specialized ovipositors to make small incisions for the eggs to settle. These eggs then hatch, giving rise to tiny cicada nymphs.
Once hatched, the cicada nymphs fall from the tree branches to the ground, where they embark on a subterranean adventure. These nymphs, equipped with powerful front legs designed for digging, burrow into the soil to seek out tree roots. Here begins a prolonged period of subterranean existence that defines the majority of the cicada life cycle.
Cicada nymphs, with their piercing mouthparts, tap into the sap of tree roots for sustenance. Remarkably, some cicada species spend years, even decades, in this nymphal stage, feeding and growing underground. The duration of this phase can vary, with some species having shorter cycles of a few years and others, like the periodical cicadas, with remarkably long cycles of 13 or 17 years.
The subterranean nymphs eventually reach a point where molting becomes necessary. During molting, the nymphs shed their exoskeletons to reveal a larger, more mature form. This process is repeated several times throughout the nymphal stage as the cicadas continue to grow.
As the nymphs approach the end of their underground sojourn, they start to migrate closer to the surface. This migration is a prelude to the grand spectacle that awaits – their emergence into the world above ground.
The final molt marks the transformation from nymph to adult cicada. The adults emerge with soft, pliable wings that gradually expand and harden. The distinctive features of adult cicadas, including their large eyes, membranous wings, and, in males, the noisemaking structures called tymbals, become fully developed during this phase.
The emergence from the ground is a momentous event. Cicadas often emerge en masse, creating a spectacle that can be witnessed across wide areas. Once above ground, adult cicadas embark on a brief yet impactful journey. Their primary goal is to find mates and perpetuate their species.
The courtship rituals of cicadas are an integral part of their above-ground life. Male cicadas, equipped with specialized tymbals, produce distinctive buzzing sounds to attract females. The symphony of cicada calls is a defining characteristic of summer in many regions. Female cicadas respond with clicking sounds, signaling their receptivity to mating.
Following successful mating, female cicadas lay their eggs in tree branches, renewing the cycle. The eggs hatch, and the tiny nymphs fall to the ground, where they burrow into the soil to begin the subterranean phase once more. The adults, having fulfilled their reproductive mission, eventually die, and their carcasses return nutrients to the ecosystem.
Beyond their captivating life cycle, cicadas play a crucial ecological role. As they emerge in massive numbers, cicadas become a substantial food source for various predators, including birds, mammals, and even some insects. The decomposition of cicada carcasses contributes nutrients back into the soil, influencing the balance of local ecosystems.
What makes this event particularly captivating is the synchronized emergence of two different cicada broods, Brood X and Brood IX. These broods have distinct geographical ranges and periodic cycles, but their emergence occurring simultaneously is a rare and noteworthy occurrence. Scientists are eager to study this phenomenon to understand the ecological factors and evolutionary adaptations that contribute to such synchronization.
Billions of bugs to burst from the ground for first time in 221 years in US
You may be aware of the tendency of cicadas, which is to sporadically emerge in large numbers from underground every few years. For cicadas worldwide, this year is going to be a little bit different, though.
The insects come in large numbers even in normal conditions, but this year could see billions of them do so. Why, therefore, are cicadas expected to be so prevalent this year in particular?
The reason for this is that, unlike in a typical year, this one will see the emergence of two cicadas, known as Broods XII and XIX, for the first time in 221 years in the US.
Why at this particular time? Since cicadas typically emerge only every 13 or 17 years, they have a predisposition for prime numbers. This implies that they are less likely to synchronize and that predators may have trouble keeping up with them.
Actually, 221 years have passed since the 13 and 17-year cycles last connected. Maths professor Hannah Fry stated:
Thirteen years and 17 years are special because they’re both prime numbers, which means it’s really hard for a predator to have a cycle that syncs up with them. Also, they almost never synchronise with each other - 13 and 17, kind of missing each other - apart from every 221 years.- Professor Hannah Fry
Therefore, there will be two massive groups of cicadas emerging rather than just one, which would indicate seemingly apocalyptic numbers of cicadas.
A mind-altering fungus may spoil the fun for some cicadas when they emerge from the earth, shed their exoskeletons, and soar to the heavens to mate.
As it exclusively affects cicadas with a 13-or 17-year cycle, unfortunate Broods XII and XIX may be in for a very difficult time. Less than 30 years after the signing of the Declaration of Independence, in 1803, 13 and 17-year broods of cicadas simultaneously emerged.
The United States purchased 530 million acres of land from France in 1803 for $15 million, making it a landmark year for the country. Despite the fact that many states, like Texas and California, remained outside of the union, this significantly increased US territory in the west.
The Napoleonic Wars were about to begin in Europe and Thomas Jefferson was the US president when the cicadas last came out in this fashion.
Brood X primarily emerges in the eastern United States, covering areas from Georgia to New York. On the other hand, Brood IX emerges in the southern states, including North Carolina, Virginia, and West Virginia. The simultaneous emergence of these two broods paints vast regions with the mesmerizing sight and sound of billions of cicadas emerging en masse.
The impact of this event extends beyond mere curiosity. Cicadas play a vital role in the ecosystem, influencing nutrient cycling and providing a significant food source for various predators, including birds and mammals. While the emergence can be a spectacle, it is also a key moment in the natural cycle, influencing the balance of local ecosystems.
Upon emerging from the ground, cicadas undergo a remarkable transformation. Nymphs shed their exoskeletons, revealing the adult form with wings. The distinctive buzzing sound emitted by male cicadas is a crucial element of their mating ritual. The sheer volume of these calls creates a symphony that reverberates through the landscape. Female cicadas respond with their own clicking sounds, and the synchronized courtship dance begins.
The mating process is not only a spectacle but also a crucial aspect of the cicada life cycle. Female cicadas lay their eggs in the branches of trees, and the hatched nymphs will then return to the soil to begin the cycle anew.
The rare occurrence of Brood X and Brood IX emerging together provides a unique opportunity for scientists to delve into the mysteries of cicada biology. Researchers are keen on studying the genetics, behavior, and environmental cues that contribute to the synchronization of these distinct broods. Understanding these aspects can offer valuable insights into the evolutionary strategies of cicadas and their role in shaping ecosystems.
Beyond the scientific community, the mass emergence of cicadas has sparked public interest and engagement. Citizen scientists, nature enthusiasts, and photographers are documenting this extraordinary event, contributing valuable observations to scientific databases. This collaboration between researchers and the public enhances our collective understanding of cicada behavior and ecology.

One such spectacle is the simultaneous emergence of cicada broods, a rare event that unfolds with precision, signaling the end of a prolonged underground sojourn. As Brood X and Brood IX prepare to emerge in unison after 221 years, what can we expect during this extraordinary event?
The simultaneous emergence of cicada broods is not a scattered event; it occurs in specific geographical hotspots. For Brood X, the eastern United States witnessed a remarkable influx, covering areas from Georgia to New York. Simultaneously, Brood IX emerges in southern states, including North Carolina, Virginia, and West Virginia. These regions become epicenters of the cicada spectacle.
One of the most intriguing aspects of this phenomenon is the synchronized timing of its emergence. Brood X and Brood IX, despite having distinct geographical ranges and periodic cycles, align their emergence, creating a symphony of nature that spans vast areas. The precision of this timing has fascinated scientists, prompting investigations into the environmental cues and evolutionary adaptations that govern the synchronized life cycles of these cicada broods.
As the cicadas emerge, they bring with them a captivating visual display. Adult cicadas, with their large, reddish-brown bodies and distinctive red eyes, blanket the landscape. The sheer density of cicadas creates a surreal scene, transforming trees and other structures into living canvases adorned with these unique insects.
The signature soundtrack of cicada emergences is the buzzing sound produced by the males. Equipped with specialized structures called tymbals, male cicadas generate a rhythmic and mesmerizing chorus. This symphony is not just a random cacophony; it is a carefully orchestrated courtship call. The buzzing serves as an invitation to potential mates, creating a dialogue that reverberates through the air.
The simultaneous emergence sets the stage for intricate courtship rituals. Male cicadas engage in vibrant displays to attract females. The synchronized nature of the emergences enhances the chances of successful mating, as the abundance of individuals creates an environment conducive to courtship and reproduction. Females respond to the male calls, and the intricate dance of nature unfolds.
After successful courtship, female cicadas embark on the next phase of their life cycle: egg-laying. They utilize their specialized ovipositors to deposit eggs on tree branches. This process is vital for the continuation of the cicada life cycle, as the hatched nymphs will eventually return to the soil to start the underground phase anew.
The massive emergence of cicadas triggers a feeding frenzy among various predators. Birds, mammals, and even other insects take advantage of the abundance of these nutrient-rich insects. The cicadas become a crucial food source, influencing the local ecology and providing sustenance for a diverse array of wildlife.
