In a rare natural phenomenon not witnessed since 1803, the eastern United States is currently being invaded by billions, if not trillions, of cicadas. These noisy flying insects, measuring one to two inches in length, have recently emerged from the ground and have been spotted buzzing around North Carolina and South Carolina. This invasion is expected to spread across 15 other states over the coming months.

This remarkable event marks the first time in 221 years that two types of cicadas, known as brood XIX and XIII, have simultaneously risen from the ground. With their sturdy bodies, bulging red eyes, and membranous wings boasting a three-inch wingspan, these ancient creatures are captivating observers across the affected states.

According to the United States Forest Service, the two broods of cicadas will appear in parts of 17 states, including Alabama, Arkansas, Georgia, Iowa, Indiana, Illinois, Kentucky, Louisiana, Maryland, Missouri, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, Virginia, and Wisconsin.

Videos shared across social media showcase the swarms of cicadas climbing trees, flying under the lights of canopies, and crawling along the ground, mesmerizing viewers with their synchronized movements.

Eric Benson, a professor emeritus and extension entomologist at Clemson University, describes the cicada emergence as a "pretty amazing phenomenon" and one of nature's coolest phenomena. These insects are known for their incredibly long life cycles, spending either 13 or 17 years underground before emerging in unison, presenting a remarkable sight to behold.

Contrary to popular belief, cicadas are not harmful to humans, pets, gardens, or crops. In fact, they serve as a valuable food source for birds and mammals. Native Americans have historically consumed cicadas due to their rich protein content, an unexpected bounty that has provided sustenance for generations.

The peak activity period for these buzzing insects is expected to continue through early June. Typically, cicadas emerge after a heavy rainfall when the ground temperature reaches 64 degrees Fahrenheit. They then climb surfaces such as trees, houses, cars, or fences to shed their skins and transform into their winged adult forms.

During this time, the cicadas will engage in a frantic mating frenzy. Females will deposit their eggs onto tree branches, and the resulting offspring will fall into the ground to begin another multi-year cycle. In some areas, the cacophony of mating cicadas will reach sound levels equivalent to a gas-powered lawnmower or motorcycle.

While homeowners may need to contend with the unpleasant odor of decaying cicada carcasses, the EPA advises covering young trees with mesh or netting to protect them from potential damage caused by females laying their eggs on small branches. Homeowners are also encouraged to shield pools, patio furniture, and other outdoor items from cicadas and their droppings.

This extraordinary cicada invasion offers a unique opportunity for residents of the affected states to witness a natural spectacle that won't be seen again until 2244. As nature unfolds its wonders, communities are reminded to appreciate the role these ancient insects play in the ecosystem and marvel at their enduring presence.
