The Leafcutter Ants: Civilization by Instinct, Paperback/Bert Holldobler

The Leafcutter Ants is the most detailed and authoritative description of any ant species ever produced. With a text suitable for both a lay and a scientific audience, the book provides an unforgettable tour of Earth's most evolved animal societies. Each colony of leafcutters contains as many as five million workers, all the daughters of a single queen that can live over a decade. A gigantic nest can stretch thirty feet across, rise five feet or more above the ground, and consist of hundreds of chambers that reach twenty-five feet below the ground surface. Indeed, the leafcutters have parlayed their instinctive civilization into a virtual domination of forest, grassland, and cropland--from Louisiana to Patagonia. Inspired by a section of the authors' acclaimed The Superorganism , this brilliantly illustrated work provides the ultimate explanation of what a social order with a half-billion years of animal evolution has achieved.
