“Morph” means change, yet for this family of butterflies it has a different connotation. The Morpho butterflies are so named for their beauty and shape, in reference to Aphrodite. Images of these creatures require patience because when they are visible, they spend most time in the air, rarely settling on a plant long enough to focus and capture (photographically).
