The cicada brood known as Brood XIV has been recorded since 1634, first documented by William Bradford. This brood re-emerges every 17 years, currently making its presence felt across 15 states starting late April. The cicadas, often reaching 1.5 million per acre, will heavily populate tree-covered areas in the southeast U.S. for a short period before dying off and laying eggs for the next emergence. Interestingly, multiple cicada broods exist, with a staggered cycle of appearances every 13 or 17 years. This highlights the complexity of cicada life cycles beyond Brood XIV.
The first recorded American sighting of the cicada brood known as Brood XIV was made by William Bradford in 1634, where he noted their impressive numbers and constant yelling noise.
Brood XIV will make its second 21st-century appearance this year, beginning in late April, and is expected to cover 15 states before vanishing in mid- to late-June.
On average, about 1.5 million cicadas occupy every acre of tree-covered land during their emergence, resulting in potentially billions across the southeast U.S.
There are actually 15 different cicada broods, with 12 on a 17-year cycle and others appearing every 13 years. Their emergences are staggered.
