A richly illustrated guide to wasps around the world. Wasps have been around since before the dinosaurs and are one of the world's largest insect groups. More than 150,000 species have been identified, and while the black-and-yellow insect with a cinched waist may be the most familiar, most wasps are tiny parasitoids that use other insects for food. Wasps of the World provides a breathtaking look at the diverse characteristics, habitats, and lifestyles of these extraordinary insects.
