Origins of Broods XIX and XIII: Which States Do They Emerge From?

Every 17 years, a remarkable natural phenomenon occurs in several states across the eastern United States: the emergence of Broods XIX and XIII of the periodical cicadas. These insects are known for their long underground development and simultaneous emergence in massive numbers, creating a deafening chorus of buzzing and clicking sounds that can be heard for miles.

Broods XIX and XIII of the periodical cicadas are part of a unique cycle that has fascinated scientists and nature enthusiasts for centuries. These Broods are distinct from one another in terms of their emergence patterns and geographic distribution, but both follow a similar life cycle.

Brood XIX, also known as the Great Southern Brood, emerges every 13 years and can be found in states such as Georgia, Mississippi, Tennessee, North Carolina, and Alabama. This brood is known for its large numbers and loud mating calls, which are produced by the males to attract females for mating.

Brood XIII, on the other hand, emerges every 17 years and can be found in states such as Illinois, Indiana, Iowa, Wisconsin, and Michigan. This brood is also known for its massive numbers and synchronized emergence, which can sometimes reach millions of cicadas per square mile.

The emergence of Broods XIX and XIII is a sight to behold, as the landscape becomes covered in the buzzing insects and the deafening cacophony of their mating calls fills the air. Despite their intimidating appearance, periodical cicadas are harmless to humans and most plants, as they do not bite or sting and only feed on sap from trees.

Scientists study the emergence of Broods XIX and XIII to better understand their life cycle, behavior, and ecological impact. The massive numbers of cicadas can provide a food source for predators such as birds, reptiles, and mammals, and their tunneling activities can aerate the soil and help distribute nutrients to plant roots.

For nature lovers, witnessing the emergence of Broods XIX and XIII is a rare and awe-inspiring experience that highlights the beauty and complexity of the natural world. The synchronized emergence of these periodical cicadas serves as a reminder of the interconnectedness of all living organisms and the delicate balance of ecosystems.

So if you happen to be in one of the states where Broods XIX and XIII emerge, be sure to take some time to marvel at these incredible creatures and appreciate the wonders of nature that surround us.
