When do cicadas leave Illinois?

With reports of live cicadas winding down and sightings of the dead insects on the increase, many people wonder what’s coming next. Here’s what to expect.

When do the cicadas go away?

The remaining periodical cicadas out now should be gone by late June. Periodical cicadas are among the longest-lived insects on the planet, but most of their 13- or 17-year lifespan is spent underground. After emerging, singing and reproducing, the adults don’t live long. After about a month, the cicadas begin to die.

Their departure can be memorable. In 1990, there were reports of people in Chicago using snow shovels to clear sidewalks of dead cicadas, which have a noticeable odor.

Do cicadas come out every year?

Some cicadas do show up every year. Annual — or dog-day — cicadas emerge during the heat of summer, usually around July, said Kacie Athey, a specialty crops entomologist with the University of Illinois Extension.

The periodical cicadas that are dying off now were part of a historic dual emergence of two particular broods, an event that hadn’t occurred since 1803 and made Illinois the center of attention for cicada watchers. In some years, no periodical cicadas emerge. After 2024, Brood XIII and Brood XIX cicadas won’t sync up their emergences again until the year 2245.

Do cicadas have a purpose?

Cicada nymphs aerate the soil. The emergent adults prune mature trees and provide an abundant source of food for wildlife — and some humans. After they die, cicadas’ bodies provide a source of nitrogen for growing trees. CicadaMania.com breaks down the bugs’ many benefits.

Storms bring damaging winds and heavy rains to central Illinois


PEORIA, Ill. (WMBD) — Multiple rounds of severe storms impacted central Illinois on Wednesday bringing damaging wind gusts and very heavy rain. Our area was sparred from the worst of the tornadoes, but areas south of I-72 were not so fortunate with damage to homes and injuries reported.

An outflow boundary from our morning storms struggled to get any further north than highway 136, which was about 30 miles south of what was anticipated early this morning. This kept the risk of strong tornadoes just south of our local region, though we still had plenty of rain and instances of large hail and gusty winds roll through central Illinois.

The worst of the wind came with the storms in the morning. As the severe storms moved through the area they produced measured gust of 60-70 mph with localized gusts estimated to be around 80 mph. The winds resulted in tree, powerline, and structural damage from Knox through McLean County.

Storm Reports

Galesburg – Tree and power line damage
Williamsfield – Roof partially torn off building
Princeville – Tree damage
Dunlap – 60 mph wind gust
Bellevue – 60 mph wind gust
Germantown Hills – Trees down
Roanoke – 60 mph wind gust
El Paso – Power poles snapped
El Paso – Multiple semis and campers rolled on I-39
Gidley – 70 mph wind gust
