On the cover: Beginning in late May and peaking in early June, periodical cicadas (Magicicada spp.) will

emerge from the ground to sing and mate in natural areas across Lake County and Chicagoland. Here, an adult cicada makes a pit stop on the richly colored flowers of blue wild indigo (Baptisia australis).

Every spring is unique in your Lake County Forest Preserves, as habitat restoration efforts completed over the winter help promote new growth.

Rare plants once thought to BUFFALO CREEK no longer exist in the region suddenly resprout in a remnant habitat after a prescribed burn. Roadsides near preserves once crowded with invasive species flourish with diverse native plants following major clearing projects.

Birdsong returns to the trees. Flowers return to the ground. Warmth returns to the air. There is always a sign of progress, a silver lining, a beautiful moment to be found in nature.

Yet this spring promises a special event that hasn’t occurred in 221 years. Two broods, or groups, of periodical cicadas—known as Brood XIII (13) and Brood XIX (19)—will emerge by the millions during late spring in Illinois. Such a dual emergence last occurred in 1803 when Thomas Jefferson was president. Broods XIII and XIX won’t meet again until the year 2245.

This issue delves into the magic of periodical cicadas. Specific environmental conditions are needed to trigger their impressive emergence. Their life cycle holds interesting parallels to that of humans. Their synchronized songs make the treetops buzz. Along the way, enjoy beautiful, photorealistic illustrations of this true bug by Lake County artist Samantha Gallagher.

At a moment like this, I like to pause to appreciate the vision of past Lake County board members, civic and business leaders and residents. Without their efforts, the Forest Preserves would not exist. Cicadas and thousands of other species would have far fewer places to live in peace.

We’ll be celebrating cicadas throughout spring and summer with public programs and events, including a special exhibition titled Celebrating Cicadas at the Dunn Museum (Libertyville). I hope you’ll join us to gain a deeper understanding and appreciation for cicadas during this once-in-several-lifetimes moment.

However you choose to celebrate spring, enjoy all your forest preserves have to offer.

The Emergence of Periodical Cicadas

The alarm clock is ready to ring for the periodical cicadas of Lake County.

The previous mass emergence of these impressive bugs in 2007 set the alarm for 2024. During spring and summer 17 years ago, millions of cicadas tunneled out of the soil, crawled up trees, sang, mated and completed their life cycle.

This will be a magical year for their offspring.

Three 17-year species live in Lake County: • Linnaeus’ 17-year cicada (Magicicada septendecim) • Cassin’s periodical cicada (Magicicada cassini) • Decula periodical cicada (Magicicada septendecula) They’re harmless to humans and pets, and don’t bite or sting. Adults measure about 1.5 inches long. Except for different orange-brown stripes on their undersides, the species look identical. Learning their distinctive songs is the best identification method.

A brood is a group of cicadas that emerge together at regular intervals. Lake County’s periodical cicadas are in Brood XIII (13), spanning portions of Illinois, Indiana, Iowa and Wisconsin. Nationwide, there are 12 broods of 17-year cicadas and three broods of 13-year cicadas.

American Indians observed cicadas centuries before Europeans arrived. A 1634 journal entry by William Bradford, then governor of New England’s Plymouth Colony, documented cicadas.

Brood XIII’s 17-year emergence coincides with that of Brood XIX’s (19) 13-year emergence for the first time since 1803, when Thomas Jefferson was president of the United States. Tecumseh’s confederacy, a confederation of American Indians living in the Great Lakes region, also began forming in the

When ready for the final stage of their life cycle, two factors nudge the nymphs to begin their ancestors’ mating rituals. They sense the upward flow of sap, needed to sprout new springtime leaves, from the trees’ roots toward their crowns.

In late May and early June, once the temperature of the upper 8 inches of soil reaches 64 degrees Fahrenheit, the nymphs dig skyward. They don’t emerge simultaneously. South-facing locations with plentiful sunlight will see the early bugs.

Over several weeks, the cicadas will debut in such numbers they’ll be impossible to ignore. Rather, they should be celebrated.

Nicknamed the Great Southern Brood, Brood XIX “contains four cicada species on a 13-year cycle,” Hurley said. They’ll overlap most near Springfield.

The broods won’t meet again until the year 2245.

The cicadas heard every summer are annual cicadas (left). Though their life cycles last 2–5 years, they’re staggered, so some individuals are ready to emerge and sing every year.

CICADA LIFE CYCLE Artistry & Entomolog y

1

The life cycle begins when a female cicada lays eggs inside small cuts near the tips of tree branches.

2

Look for rice-shaped eggs.

Shortly after hatching, nymphs depart the treetops and drop to the ground. The race is on to burrow into the soil.

We commissioned Samantha Gallagher, a local freelance illustrator, to create 11 cicada illustrations, shown on these pages. At her home studio in Lake County, the artist uses colored pencils, pastels and textured paper to showcase cicadas, bees, moths and more.

Gallagher’s enthusiasm for insects earned her a nickname in second grade: the bee girl. “I needed to get more people to realize how cool bugs were,” she said.

In adulthood, Gallagher earned a bachelor’s degree in graphic design and a master’s degree in entomology, the study of insects. She blends them in her work today as a freelance scientific illustrator.

Nymphs sip sap from tree roots for 17 years before emerging. If a root runs dry, a nymph will leave

it and dig to find a fresh root.

Nymphs sometimes create short chimneys as they surface. Their emergence holes provide natural aeration to the soil.

Before pressing pencil to paper, Gallagher consults insect specimens and reference photos, and visits local natural areas. The research phase can take a full day per illustration. She composes a digital sketch, traces it on paper and adds layers of color.

Depending on size and complexity, she spends 8–20 hours fleshing out each drawing.

The results are beautiful, photorealistic illustrations. “There’s not a lot of room for interpretation in scientific illustration. You have to make it appealing and accurate.”

Gallagher encourages observers to “try to coexist” during the emergence.

“This happens once every 17 years,” she said. “The cicadas deserve this brief moment of glory after waiting so long.”

After emerging from the ground, the nymphs climb up a tree and shed their exoskeleton in a final molt. Their bodies are

Prime Numbers Why did periodical cicadas evolve such long life cycles? They “give the insect an edge over its predators, which typically have shorter life cycles,” said Environmental Educator April Vaos. Multiple generations of predators have never experienced a cicada emergence.

The crunchy buffet represents a survival strategy called predator satiation. It’s safety in numbers.

So many cicadas surface that predators—including birds, reptiles, mammals, frogs and fish—can’t

“The chorus attracts females ready to mate. When a male and female get close to each other, the male makes a call. The female flicks her wings to show she’s interested,” said Kritsky. This repeats a few times. “After mating, in the next couple days, she’ll lay 400–600 eggs.”
