Periodical Cicadas Broods of Illinois 2024
A Visual Guide to 2024's Rare Dual Appearance
This year, the Chicago region will see a remarkable natural phenomenon that has not occurred in over a decade: the emergence of two broods of periodical cicadas. Broods XIII and XIX will be coming out of the ground at the same time, creating a once-in-a-lifetime opportunity for nature lovers and scientists alike.
Brood XIII
Brood XIII is a group of periodical cicadas that have been living underground for 17 years. They will emerge in mid-May to early June in Illinois, Indiana, Ohio, and Michigan. These cicadas are olive green to black in color with red eyes and veins on their wings.
Brood XIX
Brood XIX is a group of periodical cicadas that have been living underground for 13 years. They will emerge in late June to early July in Illinois, Missouri, Iowa, and Kansas. These cicadas are dark brown to black in color with yellow eyes and veins on their wings.
The Dual Emergence
This year's dual emergence is a rare event that has only happened a few times in the past. The last time it occurred in the Chicago region was in 1956. The emergence of two broods at the same time will create a cacophony of sound as the cicadas sing their mating calls.
Conclusion
The emergence of periodical cicadas is a reminder of the interconnectedness of nature and the resilience of life. These insects spend most of their lives underground, but they emerge in spectacular fashion to reproduce and continue the cycle of life. The dual emergence in 2024 is a unique opportunity to witness this amazing natural phenomenon.
