Things have changed. Even crickets don’t chirp like they did in the old days. If you think the beat of the summer insects doesn’t sound like it used to, you could be right because the high-pitched songs of insects become inaudible to aging ears.
This is where The Songs of Insects comes in. It is a gorgeously illustrated visual guide to crickets, cicadas, katydids and grasshoppers, with each insect photographed on a natural surroundings and also on a white background, making them very easy to see and differentiate. It also promises to “shower you with auditory pleasures untold” and it lives up to this promise very well through the enclosed CD with the songs of almost eighty species of insect. The authors’ system of “electronics and sensitive microphones” that they used to record the insect songs means that we can listen to insect songs that we can no longer hear in the wild.
Before the guide portion of the book there are several pages of enlightening information about the classification of singing insects and the biology of insect songs. It includes some fascinating tidbits, for instance that some insects are left-handed vs. right-handed singers and their handedness (or wingedness?) is determined by species. Although we call them “songs,” insects have no lungs, so most rub wings or bumps or other modified body parts together to produce their chorus. Cicadas are different because their sound producing organs or “tymbals” resonate like drums, which explains how they can be so loud.
Each insect’s page includes sonograms or “sound pictures” for the technically minded. I was delighted to learn that “each species has its own distinct song, which is recognized by all individuals of the same species” and that pulse rates of songs vary by temperature and songs tend to speed up as the temperature rises so you can use the song to estimate temperature! But the best tidbit of all is discovering that there is an insect enchantingly called the Slightly Musical Conehead (Neoconocephalus exiliscanorous).
The Songs of Insects is a must-read for nature lovers, especially those who like to use books to identify the wildlife around them, like Sibley’s Birding Basics, by David Allen Sibley, or more quirkily, Magical Mushrooms, Mischievous Molds, by George W. Hudler. If you aren’t on the East Coast of North America you won’t necessarily be able to hear all these insects in the wild, but you can enjoy them on the CD.

The Songs of Insects is also a wonderful book for photographers. The authors explain the equipment they used and how they photographed a living creature that isn’t interested in a modeling contract and may hop away at any moment (the answer is to use a custom made “whitebox.”)
