Cicada Brood XIX and Brood XXIII to Emerge in Synchronized Event
Historical Convergence
This spring, the Midwest and Southeast will witness a remarkable entomological phenomenon: the synchronized emergence of Brood XIX and Brood XXIII cicadas. This unprecedented double emergence, occurring for the first time since 1803, marks a significant event in the lives of these 13- and 17-year cicadas, respectively.
Geographic Distribution
Brood XIX, the 13-year cicadas, will primarily emerge in Georgia and the Southeast. According to the USDA Forest, blue counties on the provided map indicate the expected locations for Brood XIX. Brood XXIII, the 17-year cicadas, will emerge in the Midwest, primarily in Illinois, Indiana, Michigan, Minnesota, Missouri, and Wisconsin.
Unique Behaviors
Cicadas are known for their distinctive songs and swarming behavior during emergence. They emerge from underground tunnels after spending years as nymphs, feeding on tree sap. The males sing to attract mates, creating a chorus of buzzing sounds that can be deafening. The females lay eggs on branches, and the nymphs hatch after about six weeks before dropping to the ground and burrowing underground.
Potential Hazards
While cicadas are generally harmless, they can be a nuisance due to their sheer numbers and loud songs. Some people may experience allergic reactions, and their nymphs can damage tree roots. However, these insects also provide a valuable food source for wildlife and play a role in nutrient cycling.
Conclusion
The synchronized emergence of Brood XIX and Brood XXIII cicadas this spring is a testament to the intricate synchronicity of nature. This extraordinary event, happening for the first time in over two centuries, is a reminder of the beauty and wonder that can be found in the most unexpected moments. As we marvel at these fascinating creatures, let us appreciate the biodiversity and resilience of the natural world.
