To date, more than a million insect species have been described, with probably at least another 5-8 million species waiting in the wings for a name. Insects are a fascinatingly diverse and beautiful spectrum of animals. They range in size from the tiny parasitic wasp, measuring a mere 139µm, to the aptly named Titan beetle, which can reach lengths of up to 17cm. They can be found on all continents of the world, from the Sahara Desert to the frozen wastes of Antarctica. While no insects live beneath the waves, the intrepid sea skaters skim the surface of some of the world's oceans. This Very Short Introduction explores the extraordinary world of insects. It analyses insect evolution, taxonomy, and development, and describes their behavior, their life styles, and the interactions they have with other insects and other animals. As Simon Leather shows, insects are the bedrock on which human civilization rests; without them we would almost certainly not exist. Although they can be seen as pests of our crops plants, they are also invaluable for pollinating our flowering plants and are an invaluable link in all land ecosystems. As they face challenges from climate change and pesticides it has never been more important to understand these oft-dismissed creatures.Mostra libro
