The Morpho butterflies are among the largest in the world, with a wingspan of 7.5 to 20 cm. The males have beautiful metallic blue upper wings, while the females are drab. Their iridescence stems from the microscopic structure of their wings. Pilots flying over the rain forest can occasionally see brief flashes of blue as these butterflies travel above the forest canopy.

Pictured is the Blue Morpho butterfly (Morpho menelaus). This brilliant blue butterfly can be found in the rain forests of Brazil and Guyana.

Read here about how and why they are so bright blue.
