For The First Time In 221 Years, A Rare Double Emergence Of Cicadas Is Expected In 2024 In Illinois

There isn't much about Illinois nature that I don't like — perhaps the only things I can think of are mosquitoes and cicadas. I expect mosquitoes, but I'm always surprised when the cicadas roll around. This year, much to my dread, there will actually be a historic double emergence of cicadas in Illinois, meaning two broods will appear at once. So get your earplugs and buckle up; here's everything you need to know about the double emergence of cicadas in 2024.

First of all, get used to seeing this tiny bug-eyed face because it's going to be everywhere this year in Illinois. Yay...

The flying bugs are known for their incredibly loud buzzing chorus, clumsiness, and volume of visitors. While they're mostly harmless, their eggs could cause a good amount of damage to newly planted orchards, according to experts.

Specifically, we'll be seeing the emergence of the periodical cicada brood known as Brood XIII. That group should begin appearing around late May and last about four weeks until the end of June. The brood is substantial and has a reputation as being the biggest emergence of cicadas all-around.

But that's not all. We'll also be seeing an emergence of the Great Southern Brood known as Brood XXIX. These guys are found more in the lower half of the state, particularly in Eastern and Western Illinois.

Having these two broods come out at once is a rare phenomenon that occurs once only every 221 years.

Often, you'll notice the cicada in two forms: its colorful, active form and the brown shell forms that they leave behind.

These shells are left eerily gripping onto trees, twigs, and stems as they are shed. It's not uncommon for me to accidentally crunch one under my shoe that's fallen off a tree onto the sidewalk, sending shivers up my spine.

Think you're ready for the double emergence of cicadas in 2024? This isn't the first time Illinois has prepared for an onslaught of these noisy, buzzing creatures — though, to be fair, some people love the little fellas.
