It's a battle 17 years in the making—as millions of Cicadas start to emerge from holes in the ground.
The ground, now warm enough for the return of the most anticipated insect of the summer.
Right now, the Brecksville Reservations is ground zero for the winged warriors.
"They will be around for the next four weeks as adults, mating laying eggs," said Sharon Hosko, of the Brecksville Nature Center.
They're starting to show up around town, but it will still be a bit before we hear them.
Their bodies need to harden for a few days after breaking out of their shell.
So how do Cicadas know this is the year for them to return?
"It's built in their DNA," says Hosko.
