Two Broods to Wake Up During the Same Season

This year, a rare event is about to unfold as two groups of periodical cicadas, known as broods, are waking up during the same season. Brood XIX and Brood XIII will emerge in 2024, bringing trillions of these noisy insects to the surface after 13 and 17 years underground, respectively.

Interactive Map to Locate Brood XIX and Brood XIII

An interactive map from the University of Connecticut provides a detailed overview of the areas where these broods will emerge. You can use the map to identify the specific counties and states that will be affected by the massive cicada emergence.

The 13-year cicadas of Brood XIX will primarily emerge in Georgia and the Southeast, while the 17-year cicadas of Brood XIII will appear in states including Indiana, Illinois, Missouri, and Tennessee. A total of over a dozen states will be abuzz with the distinctive sound of cicadas.

Metrics Determining Emergence Timing

Axios Visuals has calculated three factors that could influence the timing of the cicada emergence: soil temperature, precipitation, and day length. These metrics will help scientists predict the precise time when the cicadas will start to appear.
