Butterflies are disappearing. We rarely see blues, chessboard butterflies, or swallowtails anymore. The small fire butterfly and the sail butterfly have already largely vanished. Pesticides, over-fertilization, and monocultures are taking a toll on insects. With them, the birds are also disappearing. Biologist and bestselling author Josef H. Reichholf analyzes the looming ecological catastrophe. However, he also takes us into the wonderful world of butterflies. It is a passionate plea for the protection of butterflies, for example, through biotopes in every community. This book captivates us, just as Nabokov once did, with the fascination of these enchanting creatures.
