Cicadas may emerge earlier in Illinois as climate changes, experts say


As Illinois awaits a massive, rare double-brood emergence of cicadas, entomological research shows that the insects may come earlier.

This year, two ‘periodical’ cicada species—Brood XIII and Brood XIX— will emerge simultaneously. Maps of Illinois show where each brood is expected to flourish. 

According to Jennifer Rydzewski of the Forest Preserve District of DuPage County, brood XIII occurs in the Chicago area only every 17 years, while Brood XIX occurs every 13 years.

“So the 13-year and 17-year life cycles only align every 221 years,” Rydzewski told CBS Chicago in an e-mail.

“Periodical cicadas have typically emerged in late May or early June in northern Illinois,” said Dr. Ken Johnson of the University of Illinois. However, because of the urban heat island, that might happen earlier in Chicago. 

How will cicada behavior change? 

But as Chicago bakes in its third-warmest year on record, is a species directly cued by soil temperatures warming to 64 degrees being affected by the warming climate? Some cicadas were reported last week in the northwest suburbs. 

According to the University of Connecticut’s Climate Change and Periodical Cicadas, “All available evidence indicates that the climate is warming and precipitation patterns are changing, and because some parts of the periodical cicada life cycle seem sensitive to these factors, it follows that these insects will be affected by climate change.”

That study predicts that warming climates will cause periodical cicada emergences to start earlier in the year since spring will arrive earlier as the climate warms. Climate-related disruption of the cues periodical cicadas use to pick their year of emergence will lead to an increase in unexpected, oddly-timed emergences or even the breakdown of these insects’ periodicity. 

The study mentions notable off-cycle emergences have already occurred, such as the unexpected emergence of Brood X cicadas in 2017.

“It’s possible we are a few days ahead of schedule this year due to the warming climate, but we definitely need more data and analysis,” Dr. Catherine Dana of the Illinois Natural History Survey said.

Periodical cicadas’ long life cycles and rare emergences make gathering that data a lengthy process – but the periodical cicada mapping project is trying to accomplish that goal.

However, as the Connecticut study states, “It will take a while to collect the data, and the project involves multiple generations… of cicadas and researchers alike.”

How long will cicadas be around in Illinois?

Periodical cicadas spend most of their time living underground, feeding on tree roots. Once the soil warms enough, they begin to emerge above ground.

According to the University of Illinois, adult cicadas spend most of their time above ground reproducing. Male cicadas start singing four or five days after they emerge.

After mating, the female cicadas will lay their eggs, about 500 to 600 each.

The adult cicadas will begin to die after about a month. That should happen before outdoor Ravinia Festival concerts kick into high gear. 

When will periodical cicadas emerge again in Illinois after 2024?

About six to ten weeks after they are laid, the eggs begin to hatch. The tiny cicada nymphs drop to the ground and begin feeding, often on grass roots.

Eventually, they dig into the soil about 8 to 12 inches deep and feed on tree roots for 13 to 17 years.

Sonya Massey, shot by Illinois sheriff’s deputy, died of gunshot wound to the head, autopsy finds


CHICAGO (CBS) — Authorities in central Illinois on Friday released an autopsy report that confirmed 36-year-old Sonya Massey died of a gunshot wound to the head, after she was shot by a sheriff’s deputy in Springfield earlier this month.

According to the autopsy report from the Sangamon County Coroner’s office, Massey was shot just beneath her left eye, and the bullet exited the back of her upper neck. The bullet caused a skull fracture, perforated her carotid artery, and caused bleeding in her brain.

Massey also suffered minor blunt force injuries to her right leg.

Sangamon County Sheriff’s deputy Sean Grayson has been charged with first-degree murder, aggravated battery with a firearm and official misconduct in Massey’s death. He has pleaded not guilty to all charges, and is being held in the Sangamon County Jail while he awaits trial. He was fired by the sheriff’s office after the shooting.

After learning of the autopsy results on Friday, Massey’s family said they are still struggling mentally and emotionally nearly three weeks after her death.

“I haven’t been able to sleep for real. The only time I really feel comfortable sleeping is when I’m just on the floor. I can’t even sleep in my bed,” said her son, Malachi Hill-Massey. “I really don’t have words. Like I’ve been said, I don’t have words for real.”

Massey’s uncle, Raymond, said her daughter has been “having nightmares to the point where we have to check the room.”

“It just makes me so angry to see my family hurt as they do,” Raymond said.

Bodycam video shows sheriff’s deputy shooting Massey inside her home

Authorities said Massey, a Black mother of two, called 911 in the early morning hours on Saturday, July 6, to report a suspected prowler outside her house near Springfield, Illinois.

The bodycam video shows Grayson and his partner, who are both White, arriving at Massey’s home, and searching outside the house and talking to Massey at the front door. They are later seen inside her home, and Deputy Grayson instructs Massey to check on a pot overheating on the stove, saying they don’t need a fire in the house.

Massey went to turn off the flame and picked up the pot. She asked where the deputies were going, to which Grayson replied, “Away from your hot, steaming water.”

Massey replied, “Away from my hot, steaming water?” and then twice said, “I rebuke you in the name of Jesus.”

“You’d better f***ing not. I swear to God, I’ll f***ing shoot you right in your f***ing face,” Grayson said. He then raised his gun and yelled at Massey to “drop the f***ing pot!”

Massey is seen apologizing and ducking for cover. Grayson opens fire—three shots are heard.

Massey’s family and friends claim authorities tried to cover up the fatal shooting

The family said if it weren’t for the bodycam video of the shooting that was released on Monday, no one would know the truth.

Massey’s friends and family have said police first suggested it was a neighbor who had a previous dispute with Massey who shot her, and then later suggested the shooting was self-inflicted.

Massey’s oldest son, Malachi, said no one from law enforcement ever told the family who actually shot Massey. He said he didn’t learn until he saw it on the news the next day.
