As spring approaches, the sound of cicadas will soon fill the air across many states in the eastern United States. This year, the highly anticipated Brood XIV Cicadas will emerge, marking a significant natural event that occurs every 17 years. These insects, known for their distinctive buzzing, will be a clear sign that warmer months are on the way.
What Are Brood XIV Cicadas?
Brood XIV Cicadas are periodical cicadas that appear once every 17 years. Alongside Brood XIX, which emerged in 2024, this brood is one of the largest known. Their synchronized emergence in massive numbers creates an incredible spectacle across several states.
When Will Brood XIV Cicadas Emerge?
The emergence of Brood XIV Cicadas is expected to begin in mid-to-late April, triggered by soil temperatures reaching approximately 64 to 65 degrees Fahrenheit. Their appearance often coincides with a warm rain, encouraging them to surface from the ground. Historically, these cicadas follow predictable patterns, and experts believe 2025 will be no different.
Timeline of Brood XIV Cicada Emergence by Region
- Mid-April: Northern Georgia
- Late April: Southern Tennessee and South Carolina
- Early May: Central Ohio, Northern Tennessee, Western Virginia
- Mid-to-Late May: West Virginia, Northern Kentucky, Southern Ohio, Maryland, and Massachusetts
Some sightings may also occur in Southern Indiana, depending on weather conditions.
Which States Will Experience Brood XIV Cicadas?
According to cicada expert Gene Kritsky, Brood XIV Cicadas will emerge in 13 states, including:
- Georgia
- Kentucky
- Maryland
- Massachusetts
- New Jersey
- New York
- North Carolina
- Ohio
- Pennsylvania
- South Carolina
- Tennessee
- Virginia
- West Virginia
Kentucky and Tennessee are expected to witness the highest concentration of these insects, followed by Georgia, the Carolinas, and Pennsylvania.
How Long Will Brood XIV Cicadas Stay Active?
Once they start emerging in a particular location, Brood XIV Cicadas will remain active for approximately six weeks. Their life cycle involves surfacing, climbing onto trees or vertical surfaces, and shedding their exoskeletons. As they transition into adulthood, males begin their loud calls to attract females. By July, most cicadas will have completed their cycle, leaving behind only their shells and small holes in the ground.
Will Brood XIV Cicadas Harm Gardens or Trees?
Gardeners and homeowners need not worry—Brood XIV Cicadas do not consume garden plants. Instead, they sustain themselves by drinking fluids from tree roots. While female cicadas may lay eggs on small tree branches, leading to minor damage, this natural pruning can actually be beneficial for trees, promoting healthier growth the following season.
How Do Brood XIV Cicadas Compare to Previous Broods?
While Brood XIV Cicadas will be widespread in 2025, last year’s dual emergence of Brood XIX (13-year cycle) and Brood XIII (17-year cycle) covered even more states. Another massive brood, Brood X, surfaced in 2021 across states such as Illinois, Indiana, Maryland, and Michigan. Each emergence event offers a unique chance to witness this rare natural phenomenon.
Can Cicadas Cause Itching or Mites?
There have been reports of oak leaf itch mites coinciding with cicada emergences. These mites typically appear 6-10 weeks after cicadas lay their eggs and can cause skin irritation. The simplest way to avoid any discomfort is to refrain from sitting under oak trees in July, when the mites may fall from tree branches.
Why Do Cicadas Buzz?
The buzzing noise associated with Brood XIV Cicadas is actually their form of communication. Male cicadas produce three distinct songs to attract females. This high-pitched sound is a hallmark of cicada season and can be heard for miles.
Do Brood XIV Cicadas Sleep?
There is no definitive evidence that cicadas sleep, but they do become quieter at night. Experts have observed that cicadas rest on tree branches and remain still when it’s dark, indicating a possible rest phase.
How to Track Brood XIV Cicada Sightings
For those interested in tracking cicada activity, the Cicada Safari app provides a way to log sightings and contribute to scientific research. Cicada enthusiasts can also speak with older generations to learn about past emergences and compare this year’s event to historical records.
A Once-in-a-Generation Event
The emergence of Brood XIV Cicadas is a rare event that offers a glimpse into one of nature’s most fascinating cycles. If you live in an area expecting cicadas, take the opportunity to witness this phenomenon with your family—it’s an experience that only comes once every 17 years!
