Morpho blue butterfly eating fruit, blue is a rare color in nature!

While the butterfly has a beautiful blue coloring, it doesn’t actually have any pigment to make it look that way. In fact, the blue morpho uses structural color to get its particular shade of blue.

Blue is actually an extremely rare color in nature. These butterflies have scales that overlap, refracting light similar to a prism. So, when the light hits the wings, it is refracted against the scales and comes off as blue.

Well, compared to other butterflies. Blue Morphos are some of the largest butterflies in the world, with a wingspan reaching up to 8 inches.
