Trillions of cicadas emerged across the US in what experts are calling the largest invasion in centuries. These buzzing insects, known for their distinctive sound and striking appearance, are set to emerge from the ground in numbers not seen in decades and possibly even centuries.

Tillions Of Cicadas Emerged Across The Us In What Is Being Called The Largest Invasion In Centuries

The upcoming spectacle is a result of a rare dual emergence of periodical cicadas, a phenomenon that occurs when two broods, each with its distinct 13 and 17-year cycles, coincide. These periodical cicadas, distinguishable by their black bodies and red eyes, are native to North America and can only be found in certain regions.

The last time such a convergence happened was 221 years ago in 1803, a time when Thomas Jefferson was president. Experts are dubbing the upcoming event “cicada-Geddon,” emphasizing the magnitude of this natural phenomenon. These insects, often mistaken for locusts due to their buzzing chorus, can reach volumes of up to 110 decibels, creating a cacophony that’s hard to ignore.

Already, signs of the impending invasion are evident, with cicadas forming boreholes in the red clay of Georgia. The population of Brood XIX, emerging on a 13-year cycle, is spread across the Midwest and Southeast, including states like Iowa, Illinois, and Georgia. Meanwhile, another population, Brood XIII, is set to surface in Illinois on a 17-year cycle.

The convergence of these broods means that more cicadas will emerge than ever before. Biologists estimate that trillions of these insects will cover vast territories, equivalent to the size of the state of Delaware. From Maryland to Oklahoma and Illinois to Alabama, these buzzing creatures will make their presence felt, climbing trees to mate and lay eggs before returning underground.

Describing the event as a unique experience and “a sight to behold,” experts highlight the marvel of witnessing trillions of living organisms emerge from beneath the earth’s surface. For Georgia Tech biophysicist Saad Bhamla, it’s akin to encountering an entire alien species making its presence known after years of dormancy.

As periodical cicadas make their way above ground, they seek out vegetation surrounding mature trees, where they engage in mating rituals and lay their eggs. This cycle continues as the next generation burrows underground to feast on tree roots, maintaining the natural balance of their ecosystem.

In conclusion, cicadas emerged across the US, marking a rare and awe-inspiring event. As these insects surface from their subterranean habitats, they remind us of the intricate and cyclical nature of the natural world, inviting us to marvel at the wonders of the insect kingdom.
