after 17 years of being in the ground they come out like this...
and then they come out by the thousands....and i mean thousands as in millions....and do this EVERYWHERE
and then they go up in the trees and make all that sound trying to attract mates so they can do this...
and then the females lay a bunch of eggs in the ground and those stay there for another 17 years.
i took my daughter on a walk to the back side of our property and i heard some cracking and a tall spindly tree that was totally loaded with them fell over and broke. most of the time we were walking we were having to dodge cicadas flying around and bumping into us.
these things aren't small, either. about an inch to an inch and a half.
tons of fun.
So, are they a food source for some animal or bird. Or is their only reason for being, to be really really irritating?
So they lay dormant for 17 years. And when their biological clock goes off, they come out and party like a mfer. Then lay dormant for another 17 years?
That must be one hell of a party if it takes 17 years to recuperate.
