Cicadas to Emerge in the Midwest and Southeast in 2024

Dual Emergence of Two Broods

This spring, two broods of cicadas will emerge in the Midwest and the Southeast in their first dual appearance in over 100 years. Brood XIX, a 13-year cicada, will emerge in Georgia and surrounding states, while Brood XIII, a 17-year cicada, will emerge in parts of the Midwest.

Brood XIX Emergence

Brood XIX is expected to emerge in Georgia, South Carolina, North Carolina, Tennessee, and parts of Kentucky. These cicadas have a unique life cycle, spending 13 years underground before emerging to mate and lay eggs. The last time Brood XIX emerged was in 2011, and their next emergence is expected to begin in late April or early May 2024.

Brood XIII Emergence

Brood XIII is expected to emerge in parts of Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, Ohio, Pennsylvania, and Wisconsin. These cicadas have a 17-year life cycle, making their emergence even more rare. The last time Brood XIII emerged was in 2007, and their next emergence is expected to begin in mid-May 2024.

Impact of Cicada Emergence

Cicada emergences can have a significant impact on local ecosystems. The adult cicadas feed on tree sap, and their large numbers can cause temporary leaf damage. However, the nymphs are beneficial to the soil ecosystem, and their emergence can increase soil aeration and nutrient availability.

Precaution Measures

While cicadas are not harmful to humans, their sheer numbers can be overwhelming. To minimize nuisance, residents in affected areas should: * Keep windows and doors closed during peak emergence periods. * Stay indoors during the day, when cicadas are most active. * Wear protective clothing if working outdoors. * Avoid mowing the lawn during peak emergence periods, as this can harm the cicadas.
