The Monarchs Are Missing: A Butterfly Mystery

by Rebecca E. Hirsch

Overview

Why are monarch butterflies disappearing? Scientists are racing to find answers. These iconic orange, black, and white butterflies flutter across much of the North American continent, and are a familiar summer sight in many backyards. But in the last twenty years, the monarch butterfly population has been decreasing. Why? Skilled science writer Rebecca E. Hirsch takes readers on a quest to discover what scientists already know—and what they're hoping to learn. In addition, she offers tips about what monarch lovers can do to make a difference, from planting a butterfly garden to getting the word out about harmful pesticides to taking part in citizen science projects.

"A fine choice for most public and school library collections, particularly those that promote active engagement with the natural world by citizen scientists of all ages."—School Library Journal

From the Publisher

01/01/2018
Gr 3–7—Hirsch introduces the mysteries of monarch butterfly migration while encouraging readers to get involved to halt the butterfly's population decline. The author recounts how scientists developed tagging methods to track the path of eastern monarchs and to identify their wintering grounds in Mexico. After explaining the generational life cycles required to complete the yearly migratory journey, she devotes much of the book to hypotheses about why their numbers have dropped dramatically. Among them are reduced forests in Mexico, declines in milkweed and other wildflowers along flight paths, climate change, and displacement of native milkweed by tropical species, pesticides, and herbicides. She explains how citizen scientists, including children, can participate in studies and create monarch habitats to aid butterfly survival. The included suggested books and websites reinforce the recommendations. Hirsch packs a lot of information into this volume. Her clear, conversational presentation differs from the texts in two of her previous books about monarchs (Monarch Butterfly Migration and Monarch Butterflies: A Generational Journey). Older readers, including adults, who want additional information and activity suggestions for home or classrooms might consult Kylee Baumle's The Monarch. VERDICT A fine choice for most public and school library collections, particularly those that promote active engagement with the natural world by citizen scientists of all ages.—Kathy Piehl, Minnesota State University Library, Mankato

Scientists and citizen scientists investigate monarch butterflies.The first question was where the butterflies went in the fall. After the discovery of their wintering colonies in the oyamel forests of Mexico, the question changed to why their numbers have dwindled. Scientists point to a number of possible causes: weather variations and climate change; habitat reduction; herbicide use that has reduced the population of milkweed, where monarchs lay eggs and their caterpillars feed, and other wildflowers, where adult butterflies feed during migration; widespread use of neonicotinoid pesticides; and the rise of a disease due to garden planting of a winter-blooming milkweed species that encourages the butterflies to overwinter in Southern states. Hirsch, a former biologist and graceful science writer, explains the monarch life cycle and its complex migration clearly, setting the stage for her exploration of the many mysteries that still surround the population's ups and downs. She stresses the hopeful fact that monarchs can bounce back relatively quickly, because they lay so many eggs, and she offers realistic options for readers to participate in research and to encourage butterflies. Her clear explanation is attractively presented, illustrated with stock photographs of butterflies and some human researchers (of varying ages and ethnicities) as well as with occasional appropriate charts, all supported by extensive backmatter. Sadly, the index is skimpy, a disservice.An excellent introduction to a familiar scientific puzzle.
