Mystery #1: The Monarch Migration

In Rebecca E. Hirsch’s book, readers will learn about the life of monarch butterflies, particularly their migration pattern. The migration of monarch butterflies baffled scientists for a very long time. Where did these monarchs come from and where did their migration end?

“It’s like detective work. We’re… trying to figure out what’s going on.”
— Elise Zipkin, a Michigan State University biologist who studies monarch butterflies

It was Canadian scientist Fred Urquhart who figured out a method of tagging monarch butterflies that would work. He and his wife Norah used a tag similar to the price stickers used in grocery stores.  Because they were observing migration, it would have been hard to track the butterflies. Fred and Norah enlisted the help of the public to tag the monarchs.

Here’s an interesting fact I learned in the first few pages of the book: Milkweed contains poisons, and most animals won’t eat it. But the monarch caterpillar thrives on it. The caterpillar collects the poisons in its body, and so it too becomes poisonous to many predator. The poisons will remain in its body when it becomes a butterfly.

Mystery # 2: The Missing Monarchs

Because counting monarch butterflies is such an impossible feat, scientists measure the are of their colonies. Monarchs tend to cluster together in trees (as shown in the picture above). It was fascinating to learn that their highest record was 45 acres, which is equivalent to about 34 football fields! This value was recorded in 1997.

In 2014, the colonies dropped to 1.7 acres. The book discusses the different factors that could explain the drastic decline in colonies such as climate change, deadlier winter forests, drought, and herbicides that are harming the milkweeds.

“One hopeful thing about monarchs is that they have the ability to bounce back with big numbers.” — p. 37

The Monarchs Are Missing is a great and valuable resource about monarch migration. This book helps spread the word about what is happening to monarch butterflies. Although it has a lot of text, the book comes with pictures that aid in understanding what was being talked about in a certain page. In addition to a Glossary, Rebecca Hirsch provided titles for further reading, a list of websites for people who are interested in becoming citizen scientists, as well as resources on how to plant a butterfly garden.

    I did know about the milkweed & the protection it gives to the monarchs, but my fun question is “how did they first know?” It is of interest to read a book like this that covers a stretch of time & the changes happening, and also like this, alarming. Thanks, Fats!
