Cover von Rebecca E. Hirsch: Monarchs Are Missing (PDF)

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.
