Cicadas are so bizarre. A couple of summers ago I was around Des Moines and Ames, IA and was completely baffled by the strange noise that seemed to be everywhere and yet impossible to localize. After a few days I heard someone talking about the cicadas and learned something new!
As I always tell my kids, aren't you glad they are the size they are instead of the size of a car!
Come visit Japan in August; the cicadas are so loud throughout most of the country that you have to raise your voice to be heard.
Be careful standing underneath a tree involved in ._cicida rain_.
