The author, Vincent Dethier, was a former professor in the entomology department at UMASS Amherst where I was pursuing my MS back in the 90's and was always a presence at our weekly seminars. A very venerable, cheerful, and pleasant figure, he was something of an idol to all of us. I finally tracked down his book after I had graduated and he had passed away. Being an fellow entomologist, I greatly enjoyed his descriptions of the various Orthoptera he encountered on his early ventures and could readily identify with his fascination of the creatures that sing throughout the warm months of the year. Those with a strong dislike for anything insect or who find their various songs nothing short of annoying on a summers evening will want to avoid this treatise.
