☆ A Cicada’s Guide to Periodical Romance
▼ + stars: | 2024-05-08 | by ( Alan Burdick | ) www.nytimes.com time to read: 1 min

But to the individual cicada, what’s underway is a courtship ritual as intimate and intricate as a tango. The stakes are high; the potential missteps are many. Review the guest listThis year, in a rare “dual emergence,” two groups of periodical cicadas are in attendance: Brood XIII, or the Northern Illinois Brood, comprising as many as three species of 17-year cicada in some locations, and Brood XIX, the Great Southern Brood, comprising up to four species of 13-year cicada. Their songs — like those of Magicicada septendecim and Magicicada neotredecim, below — can sound deceptively similar:

Trillions of noisy, red-eyed insects called cicadas are emerging from the earth after more than a decade of feeding on tree roots. This spring, Brood XIX, known as the Great Southern Brood, and Brood XIII, or the Northern Illinois Brood, are emerging simultaneously. The Great Southern Brood, which emerges across the South and the Midwest every 13 years, has been seen at sites scattered from North Carolina to Georgia. The Northern Illinois Brood, which appears every 17 years in the Midwest, is expected to appear in the next month, as temperatures there warm. “There’s surprisingly little information about cicadas that you’d like to know,” said Raymond Goldstein, a physicist at the University of Cambridge.

☆ Cicadas 2024: What to expect from the 2024 periodical cicada emergence and how to prepare

The insects will infiltrate a much bigger geographical area than similar occurrences in most years because they’re part of the dual emergence of two particular periodical cicada broods. Although the full-scale emergence isn’t underway yet, experts have some guidance on how to prepare for cicada season. A periodical cicada that has just shed its outer skeleton crawls among holes dug by emerging cicada nymphs on May 20, 2021, in Takoma Park, Maryland. A young tree in Takoma Park, Maryland, is draped in netting in May 2021 to protect its small branches from being damaged by periodical cicadas laying their eggs in them. It’s not clear why periodical cicadas evolved to emerge every 13 or 17 years.

☆ Cicadas 2024: What to expect from the Brood XIII and Brood XIX emergence of cicadas

The 13-year group, known as Brood XIX, or the Great Southern Brood, is the largest periodical cicada brood, stretching across the southeastern United States. The Northern Illinois Brood, or Brood XIII, emerges every 17 years. Periodical cicadas are smaller and mostly black, with bright red eyes and orange-tinged wings and legs. Billions of cicadas are expected this spring as two different broods — Broods XIX and XIII — emerge simultaneously. However, predictions of a cicadapocalypse — in which Brood XIII and Brood XIX show up at the same place at the same time — are probably an exaggeration.

☆ Up to a Trillion Cicadas Are About to Emerge in the U.S.

In a rare occurrence, a trillion cicadas from two different broods are expected to begin appearing in the Midwest and Southeast regions of the United States at the end of April. It’s the first time since 1803 that Brood XIX, or the Great Southern Brood, and Brood XIII, or the Northern Illinois Brood, will appear together in an event known as a dual emergence. Thomas Jefferson was president the last time that the Northern Illinois Brood’s 17-year cycle aligned with the Great Southern Brood’s 13-year period. After this spring, it’ll be another 221 years before the groups, which are geographically adjacent, appear together again. A roughly 16-state area will be center stage for these periodical cicadas, which differ from those that appear annually in smaller numbers.

The cicadas are coming — and if you’re in the Midwest or the Southeast, they will be more plentiful than ever. This spring, for the first time since 1803, two cicada groups known as Brood XIX, or the Great Southern Brood, and Brood XIII, or the Northern Illinois Brood, are set to appear at the same time, in what is known as a dual emergence. The last time the Northern Illinois Brood’s 17-year cycle aligned with the Great Southern Brood’s 13-year period, Thomas Jefferson was president. After this spring, it’ll be another 221 years before the broods, which are geographically adjacent, appear together again. “Nobody alive today will see it happen again,” said Floyd W. Shockley, the chair of the Entomology Collections Committee at the Smithsonian National Museum of Natural History.
