The cicadas are one of my favourite insects. I have listened to them on many occasions through out my life without knowing what a complex and intricate life-cycle they have. They remind me of the low-sounds made by Jews Harp, a small musical instrument which is held against the teeth or lips. When there are thousands of cicadas calling at once, it is like an orchestra of the Jews Harp.
I hope you enjoy this video as much as I have.
