(WOLO) Columbia, SC-It's about to get a lot noisier along parts of the East Coast. That's because it's almost time for the cicadas to reappear in states from North Carolina to Connectiuct. One bug expert says we could see as many as a billion of these insects per square mile in some places. The giant, flying insects come out from the ground every 17 years to mate and lay eggs. The males sing a loud song throughout the day...in hopes of attracting a mate.
After mating, the insects dig holes in tree branches and lay their eggs. then, they die. The eggs usually hatch six to eight weeks later, and the baby cicadas fall and burrow into the ground. They feed off the tree root's sap until it's time to come out again.
