"Newbery-Honor winning author Joyce Sidman explores the extraordinary life and scientific discoveries of Maria Merian, who discovered the truth about metamorphosis and documented the science behind the mystery in this visual biography that features many original paintings by Maria herself."--

In 1660, at the age of thirteen, Maria Sibylla Merian (1647-1717) began her study of butterfly metamorphosis years before any other scientist published an accurate description of the process. Later, Merian and her daughter ventured thousands of miles from their home in the Netherlands into the rainforests of South America seeking new and amazing insects to observe and illustrate.
