Scientist asks Illinois residents to help track cicada swarm

MAKANDA (AP) — A researcher from the University of Connecticut is asking southern Illinois residents to help document the 13-year swarm of cicadas that’s expected to hit later this month.

John Cooley plans to come to the region to track the insects’ movements, and he wants residents to crowd-source their cicada sightings and observations on his website. He tells the Southern Illinoisan that the emergence will take about a month or so, and then adult cicadas will begin singing to attract mates and flying around about a week or 10 days later.

Cooley says adults can live up to four weeks, dying after the female lays its eggs in tree bark.

After the eggs hatch, he says the young cicada burrows into the soil until it emerges in another 13 years.
