FORT WAYNE, Ind. (WFFT) — Trillions of cicadas are going to emerge later this year.
Brood X is one of the largest broods of cicadas is going to emerge after 17 years underground.
The bugs went underground in 2004 and have been feeding on sap from the roots of plants since.
A brood is a group of periodical cicadas that emerge in huge groups.
There are 12 broods of cicadas that emerge every seven years and three broods that emerge every 13 years.
15 states are going to see cicadas emerge, and Indiana is one of them.
This year will mark the reemergence after 17 years of Brood X, or the Great Eastern Brood, of periodical cicadas – those large, winged mostly harmless flying insects known for their almost deafening noise.

Late May and early June is the expected range for this brood to emerge.
The adult cicadas will lay their eggs in mature trees during this range.
Four to 6 weeks later, those eggs will hatch before heading underground until 2038.
Cicadas are known for being very noisy insects.
They can emit between 80 to 100 decibels, which is like listening to a lawn mower or a low-flying airplane.
Cicadas don't pose a threat to humans.
