You can also snap up some of the popular cicada shirts the Forest Preserve is selling in anticipation of the 2024 emergence. There are three cicada shirt designs: “Be loud. Be proud,” "Cicadageddon 2024, It's Kind of a Big Deal," and "Silence is Overrated."

This summer will be unique because broods of 17-year and 13-year cicadas are going to emerge simultaneously, which is something that hasn’t happened since 1803 and won’t happen again until 2245. The brood overlap in Illinois will mostly occur in central and southern Illinois, but it still is likely to be a noisy summer in Will County with the 17-year cicada emergence.

"Periodical cicadas are among the longest-lived insects on the planet, living for 13 or 17 years," according to the University of Illinois Extension. "They spend the vast majority of that time living underground, feeding on tree roots. Once the soil warms enough in the spring (64°F at 8 inches deep), they will begin to emerge, depending on where you are located, sometime in May or early June."

So make sure to have your T-shirts ready to don to enjoy this interesting natural phenomenon.

Youth and toddler sizes

In addition to the cicada shirt, the Forest Preserve recently added several new nature-themed shirt designs for toddlers and youth, with some matching shirts for adults. For instance, “Little Stinker” skunk shirts for children and “Big Stinker” shirts for adults. And some of the popular adult shirts, including the "Stay Trashy" raccoon shirt and the “Every Day I’m Hustlin'” turtle shirt, are now available in youth and toddler sizes.

The merchandise lineup also includes magnets, sweatshirts, tank tops, onesies with matching bibs, hats and water bottles.
