Get ready for a once-in-a-generation event! In 2024, parts of the United States will witness the emergence of not one, but two different broods of cicadas. This rare occurrence, known as a double brood, promises to be a fascinating spectacle for nature enthusiasts and casual observers alike.
What is a Cicada Brood?
Cicadas are fascinating insects known for their loud, buzzing calls that fill the air during the summer months. What makes them truly unique is their life cycle. Unlike most insects that emerge annually, periodical cicadas spend most of their lives underground, feeding on tree roots. Then, like clockwork, they emerge in massive numbers every 13 or 17 years, depending on the species.
These synchronized emergences are called broods, and each brood is designated by a Roman numeral. The 17-year cicadas are found primarily in the northeastern United States, while the 13-year cicadas are found in the southern and midwestern states.
The Double Brood of 2024
In 2024, we're in for a special treat. Brood XIII, a 17-year brood, will emerge in parts of the Midwest, including Illinois, Indiana, and Iowa. At the same time, Brood XIX, a 13-year brood, will emerge in the southeastern states, including Alabama, Georgia, and Mississippi.
This overlapping of two different broods is a rare occurrence, happening only once every 221 years (that's 13 years multiplied by 17 years)!
What to Expect
During a cicada emergence, the sheer number of these insects can be overwhelming. You'll likely hear their distinctive buzzing calls everywhere you go. The males sing to attract mates, and the combined chorus can reach decibel levels comparable to a lawnmower!
While cicadas are harmless to humans, they can cause minor damage to young trees. If you're concerned about your trees, you can protect them with netting.
A Unique Learning Opportunity
The double brood of 2024 presents a unique opportunity to learn about these fascinating creatures. You can observe their life cycle, listen to their calls, and even try to identify the different species.
"It's like having a front-row seat to a natural phenomenon that only happens a handful of times in a human lifetime," says Dr. John Cooley, a leading cicada researcher. "It's something everyone should experience at least once."
Mark Your Calendars!
The exact timing of the 2024 emergence will vary depending on location and weather conditions. However, it's expected to occur sometime between late April and early June. So, mark your calendars, grab your binoculars, and get ready to witness this incredible event!
