Synthesizes current scientific knowledge on the life cycle, behavior, spectacular migration, and conservation of this charismatic insect.

The monarch butterfly is in serious danger. More than 90% of its population has been lost in recent years due to pesticides and other human activity. This book will show readers simple ways to help save one of nature's most beautiful creatures.

“What a wonderful idea for an adventure! Absolutely inspired, timely, and important.” —Alistair Humphreys, National Geographic Adventurer of the Year and author of The Doorstep Mile and Around the World by Bike Outdoor educator and field researcher Sara Dykman made history when she became the first person to bicycle along­side monarch butterflies on their storied annual migration—a round-trip adventure that included three countries and more than 10,000 miles. Equally remarkable, she did it solo, on a bike cobbled together from used parts. Her panniers were recycled buckets. In Bicycling with Butterflies, Dykman recounts her incredible journey and the dramatic ups and downs of the nearly nine-month odyssey. We’re beside her as she nav­igates unmapped roads in foreign countries, checks roadside milkweed for monarch eggs, and shares her passion with eager schoolchil­dren, skeptical bar patrons, and unimpressed border officials. We also meet some of the ardent monarch stewards who supported her efforts, from citizen scientists and research­ers to farmers and high-rise city dwellers. With both humor and humility, Dykman offers a compelling story, confirming the urgency of saving the threatened monarch migration—and the other threatened systems of nature that affect the survival of us all.

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.

This step by step guide on the wonderful life cycle of a monarch butterfly, comes with heaps of fun facts and everything you need to know on how to create an ideal pollinators paradise in your own garden. It is an excellent A4 guide, with over 54 pages of beautiful coloured photos and in-depth information - the perfect resource book for teachers working in pre-schools or primary schools, who want to learn more to teach their students on raising healthy monarch caterpillars within the classroom or outdoors. Perhaps you're that person, like me, who treats their caterpillars as pets, and loves being in their garden connected to nature watching the magical transformation. Monarchs butterflies have rapidly become my true passion in life, and now I want to share it with children and educators. I'm hoping this will ignite a passion for Monarchs in others too, and ultimately save this beautiful species from extinction. Monarchs are truly a symbol of hope for our Planet.

The fascinating and complex evolutionary relationship of the monarch butterfly and the milkweed plant Monarch butterflies are one of nature's most recognizable creatures, known for their bright colors and epic annual migration from the United States and Canada to Mexico. Yet there is much more to the monarch than its distinctive presence and mythic journeying. In Monarchs and Milkweed, Anurag Agrawal presents a vivid investigation into how the monarch butterfly has evolved closely alongside the milkweed—a toxic plant named for the sticky white substance emitted when its leaves are damaged—and how this inextricable and intimate relationship has been like an arms race over the millennia, a battle of exploitation and defense between two fascinating species. The monarch life cycle begins each spring when it deposits eggs on milkweed leaves. But this dependency of monarchs on milkweeds as food is not reciprocated, and milkweeds do all they can to poison or thwart the young monarchs. Agrawal delves into major scientific discoveries, including his own pioneering research, and traces how plant poisons have not only shaped monarch-milkweed interactions but have also been culturally important for centuries. Agrawal presents current ideas regarding the recent decline in monarch populations, including habitat destruction, increased winter storms, and lack of milkweed—the last one a theory that the author rejects. He evaluates the current sustainability of monarchs and reveals a novel explanation for their plummeting numbers. Lavishly illustrated with more than eighty color photos and images, Monarchs and Milkweed takes readers on an unforgettable exploration of one of nature's most important and sophisticated evolutionary relationships.
