The fascinating and complex evolutionary relationship of the monarch butterfly and the milkweed plant

Monarch butterflies are one in every of nature’s most recognizable creatures, known for their bright colors and epic annual migration from america and Canada to Mexico. Yet there’s a lot 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 and every spring when it deposits eggs on milkweed leaves. But this dependency of monarchs on milkweeds as food isn’t reciprocated, and milkweeds do all they are able to 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 in regards to the latest decline in monarch populations, including habitat destruction, increased winter storms, and lack of milkweed―the last one a theory that the writer 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 in every of nature’s most important and sophisticated evolutionary relationships.
