FORT WAYNE, Ind. (WFFT) — Get ready for trillions of cicadas to emerge from the ground.
Within the next few weeks, Brood X cicadas will be above ground after being under ground for the last 17 years.
They're already coming out in the masses in Tennessee and North Carolina.
Before 1950, they used to come out at the end of May, according to the Associated Press.
Walking the dog after sunset. Thought wind was gently rustling leaves, except the noise was coming from my feet. #Cicadas are emerging. @capitalweather’s prediction was spot on. #broodx pic.twitter.com/H29ISpWPkx

Indiana is one of the 15 states impacted by this large group of cicadas.
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.

They're already being seen in central Indiana.
#Cicada reports exploding in Baltimore/DC and Cincinnati. Central/southern Indiana starting to light up too. I’m thinking Central PA sees some early risers through the first 10 days of May with the explosion starting locally around May 15th. #BroodX #CicadaSafari pic.twitter.com/8SjWlV57iL

According to NASA, the red eyed insects emerge when the soil temperature 8" below the surface reaches 64.5 degrees Fahrenheit.
When will #BroodX cicadas arrive?
Studies say 17-year cicadas emerge (on avg.) when soil 8" down hits 64.5°F.

Cicadas come out at dusk so they can avoid everything that wants to eat them.
Once off the ground, they will shed their skins and try to survive before they become dinner to ants, birds, dogs and cats.
They don't pose a threat to humans.
Cicadas will lay their eggs on the trees if they are not eaten by other animals.
The eggs will hatch 4 to 6 weeks later, and then head underground until 2038.
There are 3 different types of cicada species, and each has their own mating song.
Noise levels are going to be going up, because they are noisy insects.
Their mating songs can reach greater than 100 decibels, which is louder than a lawnmower.
Since it's so loud, it can be heard up to a mile away.
