Cicadas spend the vast majority of their lives underground feeding on tree roots and come out at the end of the 13 or 17-year cycle.

When they emerge, a cicada's #1 job is to reproduce.

To attract mates, male cicadas start buzzing loudly about 4 or 5 days after emerging from underground.

The females will flick their wings to signal to the males they want to mate.

The females lay their eggs in woody plants, shrubs, and trees. Females can lay around 500 to 600 eggs.

The eggs hatch about six weeks after they're laid, and the babies fall to the ground, eventually digging themselves into the soil, where they will remain for 13 or 17 years.

How Long Will Cicadas Be Around in Illinois



After around a month of reproducing (or spreading that STD mentioned earlier), the adult cicadas will begin to die.

If you're a person who likes to eat bugs, try grabbing up a few cicadas to eat before they die.
