When Gary Nabhan was growing up in the Indiana Dunes, Indiana, he remembered being sleepy in the middle of his class one day. Looking out the window, he studied the leaves of a tree nearby.
Nabhan, who would later find out he is color blind, thought the leaves had odd colors. And as this crossed his mind, the leaves — which turned out to be monarch butterflies — flew away. Nabhan’s lifelong fascination with pollinators had just begun. Pollinator animal species such as bees, bats and monarch butterflies are essential to biodiversity.
