Photographs of a monarch butterfly's life cycle.

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.

Examines the life cycle of a Nature Upclose: A Monarch Butterfly's Life

A young child from the northern United States spots a Monarch butterfly laying eggs and keeps watch as the eggs hatch and the new caterpillars munch away on leaves. Readers will follow along as the narrator observes the butterflies' behavior up close, including the amazing metamorphosis of caterpillars into adult Monarch butterflies and their migration to Mexico. Colorful photos, diagrams, and clear, age-appropriate text will engage young readers as they explore the life cycle, natural habitat, physical characteristics, diet, and behavior of these beautiful insects. The diary format models scientific observation and critical thinking--and encourages children to keep notebooks recording their own investigations into the natural world.
