‘Screaming’ trees spread across US as cicada brood emerges after 17 years

The cicadas of Brood XIV have become an intriguing topic of study, with researchers predicting that these periodical insects will begin emerging in as early as mid-May. This periodical species has traditionally emerged every 17 years, a fascinating pattern that helps synchronize their life cycle with environmental changes.

Cicadas of Brood XIV emerge precisely when soil temperatures reach 64 to 65 degrees Fahrenheit, a signal that signals the spring vegetable and tree-building phases. Thiszoological periodicity segments the cicada lifecycle into six broods, each species sharing a similar 17-year genome. Understanding this mechanism provides insights into evolutionary strategies to synchronize life cycles with climate change.

Historical records indicate that Brood XIV has emerged for over 200 years, with the most recent appearance in April 2023 in Georgia, as reported by Gene Kritsky, a renowned生物学家. Using a meteorological model, Kritsky predicts the emergence of this species in Ohio, West Virginia, Virginia, Pennsylvania, and Massachusetts by late May. While no individual cicada is expected to start bubbling for decades, cicada density across the United States has been expected to rise significantly, driven by climate trends.

The male cicadas of Brood XIV employ a unique behavior—one that has attracted scientists worldwide— to attract females. These males produce loud, vibratory calls, often exceeding the intensity heard in commercial jets—nearly 100 decibels. The study co-validate—发觉ized the male calls to deter a date for females raised){

Kritsky observed consumers indicating surprise at the loudness of these calls, suggesting they serve as motivate for their mating.

The females of Brood XIV are, however, busy (100% accuracy)—(sizeable of 90:10). They return to nesting cities, such as Asheville, North Carolina, before the females die. Twelve cicada broods follow a 13-year life cycle, while the remaining 15 are marked by a 17-year cycle. This evolutionary unique predicts the 17-year periodicity has closed with recent emergence.
