The Beautiful Blue Color of the Morpho Butterfly is Actually a Trick of Light | New Jersey Pest Control Experts

If you’ve ever seen a morpho butterfly then you know just how incredibly beautiful its bright blue wings are. It is one of the most stunning blue colors witnessed in the animal kingdom. But, surprise! It’s all a trick! That brilliant blue color you perceive is actually created by a trick of the light. There are no actual blue pigments creating the color on their wings. That blue is actually created by nano-level structures on its wings. The scales on the wings are special in that when light is reflected off of them the scales absorb all of the different colors in that light except for blue. That blue is then reflected back at anything watching.

The morpho butterfly’s wing color is also used for a very specific purpose. When their wings are spread, the blue color is meant to signal potential mates. When the morpho butterfly closes their wings, the outside color is a more subdued brown, which helps them blend in with their surroundings and avoid predators. They also have an eye-shaped marking on the outside to scare predators away.

Have you ever seen a morpho butterfly? Do you know of any other insects that have colors on their bodies not made from pigments?
