Overview
- In Spring 2024, following the April 8 total solar eclipse, two broods of periodical cicadas, Brood XIII and Brood XIX, will emerge for the first time in 221 years, overlapping geographically.
- Brood XIX, known as the 'Great Southern Brood,' will cover much of the southeastern U.S., while Brood XIII, the 'Northern Illinois brood,' will emerge in northern Illinois and nearby areas.
- The cicadas are expected to start emerging in the last week of April in the southern U.S., with the emergence moving northward as soil temperatures reach 64 degrees Fahrenheit.
- Experts assure that the double emergence will not lead to a 'cicada apocalypse,' but rather a unique natural event that could become a 'generational memory.'
- The Cicada Safari app, created by Dr. Gene Kritsky, enables the public to document cicada sightings, aiding in research and understanding of these periodical insects.
