The knowledge of citizen scientists, biologists, and naturalists informs this book's coverage of every aspect of the monarch butterfly's life cycle (breeding, migration, and overwintering) from the perspective of every established monarch population (western North American, eastern North American, and Australian). In addition to presenting the most recent basic research on this species, The Monarch Butterfly contains the first publication of data compiled from two established citizen science projects, Journey North and the Monarch Larva Monitoring Project. It also reports for the first time on two major events of long-term importance to monarch conservation and biology: the creation of a larger protected area in the Mexican overwintering sites and a weather-related mortality event during the winter of 2002. Monarch butterflies are arguably the most recognized, studied, and loved of all insects, and the attention that scientists and the general public have paid to this species has increased both our understanding of the natural world and our concern about preserving it. The unique combination of basic research, background information, and conservation applications makes this book a valuable resource for ecologists, entomologists, naturalists, and teachers.

Monarch butterflies are among the most popular insect species in the world and are an icon for conservation groups and environmental education programs. Monarch caterpillars and adults are easily recognizable as welcome visitors to gardens in North America and beyond, and their spectacular migration in eastern North America (from breeding locations in Canada and the United States to overwintering sites in Mexico) has captured the imagination of the public. Monarch migration, behavior, and chemical ecology have been studied for decades. Yet many aspects of monarch biology have come to light in only the past few years. These aspects include questions regarding large-scale trends in monarch population sizes, monarch interactions with pathogens and insect predators, and monarch molecular genetics and large-scale evolution. A growing number of current research findings build on the observations of citizen scientists, who monitor monarch migration, reproduction, survival, and disease. Monarchs face new threats from humans as they navigate a changing landscape marked by deforestation, pesticides, genetically modified crops, and a changing climate, all of which place the future of monarchs and their amazing migration in peril. To meet the demand for a timely synthesis of monarch biology, conservation and outreach, Monarchs in a Changing World summarizes recent developments in scientific research, highlights challenges and responses to threats to monarch conservation, and showcases the many ways that monarchs are used in citizen science programs, outreach, and education. It examines issues pertaining to the eastern and western North American migratory populations, as well as to monarchs in South America, the Pacific and Caribbean Islands, and Europe. The target audience includes entomologists, population biologists, conservation policymakers, and K–12 teachers.
