"17-Year Cicada Emergence Sweeps U.S. Coasts: Is Your Region at Risk?"

Billions of Cicadas Emerge in Rare 17-Year Event Across U.S.

A massive emergence of periodical cicadas, known as Brood XIV, is underway across multiple U.S. states, marking a natural phenomenon last seen in 2008. These insects, which surface every 17 years, have already appeared in Kentucky, Pennsylvania, and Tennessee, with billions more expected in Georgia, Illinois, Indiana, and other states.

The Cicada Invasion

Triggered by soil temperatures reaching 64°F, the swarm will peak in early June. Forested areas may see over a million cicadas per acre. Though harmless, their deafening mating calls—up to 100 decibels—and sheer numbers can be overwhelming. Entomologist Dr. Gene Kritsky’s Cicada Safari app allows users to track their spread.

Unique Features

Brood XIV cicadas differ from annual green or brown cicadas, sporting striking black and orange bodies, red eyes, and a three-inch wingspan. They belong to one of 12 U.S. broods on 17-year cycles, with Brood XIV spanning 13 states. Only Brood X (2024) covers more ground.

Historical Significance

Cicada swarms have fascinated and unnerved humans for centuries. In 1634, Plymouth Colony governor William Bradford likened their noise to “constant yelling.” Today, social media buzzes with videos of their ear-splitting choruses.

Ecological Impact

Despite their brief 2-4 week lifespan, cicadas play a vital role. After mating, they die and decompose, enriching soil with nitrogen. Their abundance also provides a feast for birds, squirrels, and other wildlife, boosting local ecosystems.

Handling the Swarm

While pets may experience mild stomach issues if overindulging, cicadas pose no toxicity risk. Homeowners can protect young trees with mesh netting to prevent egg-laying. Closing windows and using white noise machines may help mute their calls.

By July, Brood XIV will vanish, leaving behind fertilized soil and a legacy of natural wonder. Their next return? 2042.

In short: Love them or loathe them, Brood XIV’s 2025 emergence is a fleeting, spectacular reminder of nature’s rhythms—one worth witnessing before they disappear for another 17 years.
