The night has been filled with the songs of insects for hundreds of millions of years – there are fossils of katydids dating back 165 million years that show the sound-producing structures on the wings with sufficient detail that the songs they made can be artificially re-produced. When we are outside at night, the chorus of night-singing crickets and katydids today is still something that should amaze us in all its diversity. This symphony reaches its peak in the fall each year and the concert hall at Mason Farm is one of the best places to hear this performance.
