A richly illustrated natural history of ants, covering their diversity, ecology, anatomy, behavior, and more. Plentiful and familiar, ants make up an estimated one-third of the world’s insect biomass and can be found in virtually every part of the globe, from rainforest canopies to city sidewalks. But their importance is about more than numbers: ants are fundamental species in a range of habitats, their interactions with plants, fungi, and other animals ensuring the survival of many fragile and complex ecosystems. This beautifully illustrated book explores the extraordinary diversity of ants and offers insights into their elaborate social systems, investigating the key collective and competitive behaviors that operate within their varied colony structures.
