A gorgeous picture book based on the true story of a scientist who solves the mysteries of monarch butterfly migration—with the help of schoolchildren!

A perfect story for nature lovers of all ages from the Caldecott Honor winning author of The Noisy Paint Box

Young Fred Urquhart was fascinated by insects, especially his favorite, the monarchbutterfly. He wondered where monarchs spent the winter. No one knew. After he became an entomologist (bug scientist), Fred and his wife, Norah,tagged hundreds of butterflies,hoping to solve the mysteryof the monarchs. But they soon discovered that they needed help. They started a "butterfly family," a community of children, teachers, and nature enthusiasts fromthree countries––Canada, the United States,and Mexico––to answer the question: Where do the monarchs go?

Detailed materials in the back of the book include maps of monarch migration, the life cycle of the butterfly, and the cultural relevance of monarch butterflies in Mexico, as well as information on environmental efforts towards monarch conservation.

一本根据真实故事改编的华丽图画书，讲述了一位科学家在学生的帮助下解开帝王蝶迁徙之谜的故事！这是一个适合所有年龄段的自然爱好者的故事，出自《吵闹的颜料盒》的凯迪克奖获奖作者之手。

年轻的弗雷德·厄克特（Fred Urquhart）对昆虫非常着迷，尤其是他最喜欢的帝王蝶。他想知道帝王蝶在哪里过冬。但没有人知道。在他成为昆虫学家（昆虫科学家）之后，弗雷德和他的妻子诺拉标记了数百只蝴蝶，希望能解开帝王蝶的神秘面纱。但他们很快发现，他们需要帮助。于是他们成立了一个“蝴蝶之家”，汇集了来自加拿大、美国和墨西哥三国的儿童、教师和自然爱好者一起研究这个问题：帝王蝶去哪里了？

后面还详细介绍了帝王蝶的迁移地图、帝王蝶的生命周期、帝王蝶在墨西哥的文化意义，以及保护帝王蝶栖息环境的信息。
