Double Cicada Brood 2024: What You Need to Know

In 2024, we are set to witness a remarkable natural phenomenon: the emergence of the Double Cicada Brood. This event, featuring the simultaneous appearance of two distinct broods of cicadas, is sure to capture the attention of nature enthusiasts and scientists alike.

In this article, we will explore everything you need to know about the Double Cicada Brood 2024, including what it is, where it will occur, and how it might affect you. By the end, you’ll have a comprehensive understanding of this fascinating event and why it matters.

What Is the Double Cicada Brood?

The Double Cicada Brood refers to the simultaneous emergence of two different broods of periodical cicadas. Periodical cicadas are unique insects that spend most of their lives underground as nymphs, emerging only once every 13 or 17 years to mate and lay eggs. The timing of their emergence is synchronized within each brood, resulting in massive numbers of cicadas appearing all at once.

So, in 2024, we’ll have two broods coming out at the same time: Brood XIII, which shows up every 17 years, and Brood XIX, which appears every 13 years. This overlap is a rare occurrence and promises to bring about an unprecedented number of cicadas.

Where Will the Double Cicada Brood Emerge?

The Double Cicada Brood will primarily be seen in the central and eastern United States. Brood XIII is expected to emerge in parts of Illinois, Indiana, Iowa, Michigan, and Wisconsin, while Brood XIX will be found in regions of Alabama, Arkansas, Georgia, Illinois, Indiana, States: KY, LA, MO, MS, NC, OK, SC, TN.

Why Are They Emerging Together?

The emergence of these two broods together is a result of their life cycles aligning in 2024. While Brood XIII follows a 17-year cycle and Brood XIX follows a 13-year cycle, their emergence years coincide every 221 years. The last time this went down was back in 1803, so the 2024 event is gonna be a pretty rare and thrilling thing to witness!

The Life Cycle of Cicadas

Nymph Stage

Cicadas spend most of their lives underground as nymphs, feeding on the roots of plants. This stage can last 13 or 17 years, depending on the brood. During this time, nymphs undergo several molts as they grow.

Emergence and Mating

When the time comes, nymphs tunnel to the surface and emerge, usually in late spring. They climb trees and other structures to molt one final time, transforming into winged adults. The newly emerged adults, known as tenerals, are soft and white but harden and darken within a few hours.

Adult Stage and Reproduction

Adult cicadas have a short lifespan, typically lasting only four to six weeks. During this time, males produce a distinctive, loud mating call to attract females. After mating, females lay their eggs in small slits they cut into tree branches. The eggs hatch six to ten weeks later, and the tiny nymphs fall to the ground, burrowing into the soil to begin the cycle anew.

Ecological Benefits

Despite their overwhelming numbers, cicadas play a vital role in the ecosystem. When they show up, it’s like a buffet for lots of predators – birds, mammals, and even other insects dig in! The decaying bodies of cicadas also contribute nutrients to the soil, benefiting plant growth.

Impact on Trees and Plants

While cicadas do not pose a significant threat to mature trees, their egg-laying can cause damage to young saplings and shrubs. When ladies make cuts in branches, it can actually harm or even kill young plants. Homeowners and gardeners in affected areas may need to take precautions to protect vulnerable plants.

Human Concerns

The sheer number of cicadas can be overwhelming, and their loud mating calls can be quite noisy. Additionally, their exoskeletons, left behind after molting, can litter the ground and other surfaces. However, cicadas are harmless to humans and do not bite or sting.

Preparing for the Double Cicada Brood

Protecting Young Plants

If you live in an area where the Double Cicada Brood is expected to emerge, consider taking steps to protect young trees and shrubs. You can use fine netting or mesh to cover vulnerable plants, preventing females from laying eggs in the branches.

Managing Noise and Cleanup

While the noise of cicadas can be bothersome, it’s a temporary inconvenience that lasts only a few weeks. To manage the cleanup, you can rake up and dispose of fallen exoskeletons and cicada bodies, or use them as compost to enrich your soil.

Fascinating Facts About Cicadas

Unique Sound Production

Cicadas produce their distinctive sound using specialized structures called tymbals, located on the sides of their abdomens. By rapidly contracting and relaxing muscles attached to the tymbals, cicadas create their characteristic buzzing calls.

Long Life Cycles

Did you know that periodical cicadas have some of the longest life cycles among insects, typically lasting either 13 or 17 years? This long development period helps them avoid many predators, as few animals have life cycles that match the cicadas’ emergence schedule.

Synchronization and Safety in Numbers

The synchronized emergence of cicadas in massive numbers is known as predator satiation. By overwhelming predators with sheer numbers, individual cicadas have a better chance of surviving and reproducing.

Conclusion

The Double Cicada Brood 2024 is a rare and fascinating natural event that offers a unique opportunity to witness the incredible life cycle of periodical cicadas. While their emergence may bring some challenges, such as noise and potential damage to young plants, the ecological benefits and sheer wonder of this phenomenon make it a once-in-a-lifetime experience.

By understanding what to expect and how to prepare, you can make the most of this extraordinary event and appreciate the remarkable world of cicadas.
