This Is Why Cicadas Aren’t Emerging In Moline Illinois

Parks like Loud Thunder Forest Preserve are filled with the noise of cicadas. But in certain parts of the city, the only sounds are those of the city.

The highly anticipated emergence of the 17-year cicadas is making waves across Northern Illinois, but the Quad Cities remain notably untouched by the insect invasion.

How Cicadas Survive Underground

Cicadas rely on tree roots for sustenance during their underground lifecycle. Without a long-established forest, their survival becomes untenable. “In our downtown areas, while we have nice trees in some of those areas, the density of the planting and perhaps the existence of the planting 17 years ago is affecting what we see in terms of the population now,” Swihart added.

17-Year Cicadas Emerge Across Northern Illinois, Sidestepping Quad Cities

Tommy McElrath works as an insect collections manager at the Illinois Natural History Survey and has been diligently working to follow the cicadas' emergence with the help of the iNaturalist app.

In some areas, cicada numbers show to be around 1.5 million per acre. However, not a single cicada has been recorded in the Quad Cities area. McElrath spoke with WQAD, telling them the main reason why.

“There were not any in the Quad Cities 17 years ago. So if they weren’t there 17 years ago, they’re not gonna be there this year.”

For those eager to witness the cicada spectacle, fear not—there are several nearby spots where they can be found.

McElrath told WQAD they will be easy to spot if you're near the Loud Thunder Forrest Preserve, where you may be sending your kids this summer for Boy Scout camp. He also listed off places with a high density of wooded areas like Wildcat Den or the forests west of Davenport.

Fans of the cicadas should seize the opportunity to experience their presence.

“Enjoy the cicadas while you can, they’re gonna be gone in just a few weeks,” McElrath said.
