Will Cicada Brood XIV Emerge in St. Louis in 2025? Here’s What to Know
As spring unfolds in 2025, nature enthusiasts and homeowners alike may be curious about the impending emergence of periodical cicadas. Specifically, questions arise regarding Brood XIV, a 17-year cicada brood set to surface this year.However, residents of St. Louis County can rest easy—Brood XIV is not expected to emerge in Missouri.
Understanding Brood XIV
Brood XIV is one of the largest 17-year cicada broods in the United States. These cicadas, belonging to the Magicicadagenus, spend 17 years underground before emerging en masse to mate and lay eggs. The last emergence of Brood XIV occurred in 2008, and the next is anticipated in 2025.
The emergence typically begins when the soil temperature reaches approximately 64°F, usually in late April or early May. Once above ground, adult cicadas live for about four to six weeks, during which time they engage in a flurry of mating activity, producing the characteristic buzzing sound that can reach up to 100 decibels.
Cicadas in Missouri: A Look Back and Ahead
While Brood XIV won't impact Missouri in 2025, the state has its own history with periodical cicadas. In 2024, Brood XIX, a 13-year cicada brood, emerged across parts of Missouri, including St. Louis County. This event was notable for its scale and the distinctive buzzing that filled the air during late spring and early summer.
Looking ahead, Missouri can anticipate the emergence of Brood XXIII in 2028. This 13-year brood, also known as the Mississippi Valley Brood, is expected to surface in southeastern parts of the state. Residents in these areas should prepare for another round of cicada activity, complete with the familiar sights and sounds of these unique insects.
Understanding Cicada Behavior and Impact
Periodical cicadas are known for their synchronized emergences and loud mating calls. While their presence can be startling due to sheer numbers and noise, cicadas are harmless to humans and pets. They do not bite or sting, and they are not known to transmit diseases.
However, cicadas can have an impact on young trees and shrubs. Female cicadas lay eggs by making slits in small branches, which can cause damage to young or newly planted trees. Homeowners are advised to protect vulnerable plants with fine mesh netting during peak cicada activity.
Preparing for Future Cicada Emergences
While St. Louis County won't experience Brood XIV in 2025, it's beneficial for residents to stay informed about upcoming cicada emergences. Understanding the life cycles and behaviors of these insects can help in preparing for their arrival and mitigating any potential impact on landscaping and outdoor activities.
For those interested in learning more about cicadas and their patterns, the Missouri Department of Conservation offers valuable resources and updates on local insect activity.
Conclusion
In summary, Brood XIV will not emerge in St. Louis County or anywhere in Missouri in 2025. Residents can enjoy a cicada-free spring and summer this year. However, staying informed about future broods, such as the anticipated emergence of Brood XXIII in 2028, will ensure that homeowners are prepared for these fascinating natural events.
