Introduces the physical characteristics, habits, and life cycle of the monarch butterfly.

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.

Every autumn, the monarch butterflies east of the Rockies migrate from as far north as Canada to Mexico. Memory is not their guide — no one butterfly makes the round trip — but each year somehow find their way to the same fifty acres of forest on the high slopes of Mexico’s Neovolcanic Mountains, and then make the return trip in the spring. In Four Wings and a Prayer, Sue Halpern sets off on an adventure to delve into the secrets behind this extraordinary phenomenon. She visits scientists and butterfly lovers across the country, offering a keenly observed portrait of the monarchs’ migration and of the people for whom they have become a glorious obsession. Combining science, memoir, and travel writing, Four Wings and a Prayer is an absorbing travelogue and a fascinating meditation on a profound mystery of the natural world.

For decades, as the monarch butterflies swooped through every year like clockwork, people from Canada to the United States to Mexico wondered, "Where do they go?" In 1976 the world learned the answer: after migrating thousands of miles, the monarchs roost by the millions in an oyamel grove in Central Mexico's mountains. But who solved this mystery? Was it the scientist or the American adventurer? The citizen scientists or the teacher or his students? Winged Wonders shows that the mystery could only be solved when they all worked as a team--and reminds readers that there's another monarch mystery today, one that we all must work together to solve.

Monarchs are a favorite and familiar North American butterfly, and their incredible annual migration has captured the popular imagination for generations. As populations of monarchs decline dramatically due to habitat loss and climate change, interest in and enthusiasm for protecting these beloved pollinators has skyrocketed. With easy-to-read text and colorful, engaging illustrations, Monarch Butterflies presents young readers with rich, detailed information about the monarchs’ life cycle, anatomy, and the wonders of their signature migration, as well as how to raise monarchs at home and the cultural significance of monarchs in Day of the Dead celebrations. As the book considers how human behavior has harmed monarchs, it offers substantive ways kids can help make a positive difference. Children will learn how to turn lawns into native plant gardens, become involved in citizen science efforts such as tagging migrating monarchs and participating in population counts, and support organizations that work to conserve butterflies.
