Cicadas Set to Emerge in Illinois in 2024: A Dual Brood Convergence
Brood XIII and Brood XIX to Swarm in May and June
Prepare yourself for a buzzing spring in Illinois as two broods of periodical cicadas, Brood XIII and Brood XIX, emerge from their long slumber. This unprecedented dual emergence marks a rare occurrence in the state's history.
What are Periodical Cicadas?
Periodical cicadas are a unique group of insects belonging to the family Cicadidae. They spend the majority of their lives underground as nymphs, feeding on plant roots. When the time is right, they emerge in synchronized mass emergences, creating a chorus of deafening songs.
Brood XIII and Brood XIX in Illinois
Brood XIII and Brood XIX are two separate broods of periodical cicadas that have distinct emergence years. Brood XIII will emerge in May, while Brood XIX will follow in June. Both broods will be active in Illinois, along with several other states.
Life Cycle and Biology
Periodical cicadas have a fascinating life cycle. They spend the first 13 or 17 years of their lives underground as nymphs. During this time, they molt and grow, feeding on plant roots. When the time is right, they emerge in large numbers to molt one final time and become adults.
Adult cicadas have a short lifespan of a few weeks. They emerge from the ground, molt, and then begin their primary mission: to mate and lay eggs. The males sing a distinctive mating call, which attracts the females. After mating, the females lay eggs in the twigs of trees.
Ecological Significance
Periodical cicadas play an important role in the ecosystem. Their mass emergence provides a food source for birds, bats, and other animals. They also help to aerate the soil and recycle nutrients.
Witness the Spectacle
The emergence of periodical cicadas is a captivating event. Their piercing songs fill the air, and their sheer numbers are awe-inspiring. If you happen to be in Illinois during their emergence, take the opportunity to witness this natural phenomenon firsthand.
