Get ready, nature enthusiasts! Parts of the United States are on the brink of witnessing a rare and awe-inspiring natural event: the simultaneous emergence of two massive broods of periodical cicadas. Starting around April, more than a trillion of these noisy insects will emerge from the ground, creating a truly unforgettable spectacle.
The two broods involved in this year's dual emergence are Brood XIII and Brood XIX. Brood XIII, following a 17-year cycle, is primarily found in northern Illinois, eastern Iowa, southern Wisconsin, and parts of northwestern Indiana. On the other hand, Brood XIX, with a 13-year cycle, spans a broader range across 15 states, including Alabama, Georgia, and Virginia, among others. These broods only overlap in a small area of central Illinois, making this dual emergence a once-in-a-lifetime event, last seen in 1803 and not expected again until 2245.
But what exactly are cicadas? These relatively large insects, measuring 1-2 inches long, spend the majority of their lives underground as nymphs, feeding on the xylem of deciduous trees. After years of growth, they emerge as adults to mate and lay eggs, living only a few weeks above ground. The synchronized emergence of periodical cicadas, unlike their annual counterparts, means that entire broods appear simultaneously, creating a cacophony of sound as males sing to attract females.
This year’s emergence is anticipated to begin in the southern regions of their distribution around mid-April and gradually move northward, lasting until June. The sheer number of cicadas promises not only a sensory overload with their loud choruses but also an incredible opportunity for birdwatchers and nature lovers to observe these fascinating creatures up close.
So, whether you're a young global citizen, a business and tech enthusiast, or simply someone who loves the wonders of nature, keep an ear out and look up as these trillion-strong cicadas emerge, marking a truly extraordinary moment in the natural world.
