The Mystery of the Monarchs: How Kids, Teachers, and Butterfly Fans Helped Fred and Norah Urquhart Track the Great Monarch Migration

This picture-book account follows entomologist Fred Urquhart and his wife, Norah, as they investigate where monarch butterflies spend the winter. The Urquharts developed butterfly tags and called on people across the United States and Canada, including schoolchildren, to capture, tag, release, and report monarchs. Their collected information helped them trace the butterflies’ migration to their winter home in Mexico.
