Wonderfully and copiously illustrated, communicates the current thinking on the evolution and systematics of these complex beings. Because I feel too small to review such a great book, but obviously think it should be prominent on our book list, I quote from Thomas Eisner's statement on the back cover: "A landmark contribution, not just to entomology and evolutionary biology, but to the life sciences as a whole...A must for naturalists, young and old. Truly a definitive work."
