In 1917, Amelia and Philip published their book
A Year Of Costa Rican Natural History. In the study of the fauna and flora Calvert found that many flowers would bloom in a dry season where many of these flowers would dry out. This was important where they would be a source of food for many of the insects that Philip Powell Calvert was studying such as
butterflies and
dragonflies. Her book also featured photos of villages and the indigenous peoples of
Costa Rica during her trip. Images included buildings, portraits, and traditional events alongside her flower research. ==Panama disease==
