The fall migration of the monarch butterfly is a remarkable wonder of nature. Urquhart, professor emeritus at the University of Toronto, has spent a lifetime observing and collecting data on this species. Because many of the monarch's activities depend on milkweed, Urquhart begins with a discussion of that plant's distribution; he follows with detailed information on the monarch's biology. Most fascinating is his description of an ingenious method of butterfly tagging that led to new discoveries about migration and overwintering sites. Specialists, students, and amateur naturalists will be well served by this complete, authoritative, fully illustrated text. Laurie Bartolini, Lincoln Lib., Springfield, Ill.
