Blue Morpho Butterflies

By Jamie & Jason

This is our post about blue morpho butterflies.  The reason we are doing this post is we wondered about morphos and why the top side of their wings are blue.  Also, 1st grade at our school will be studying and taking care of butterflies in the spring.

Facts about Blue Morpho Butterflies

The top side appears to be iridescent blue, but isn’t really blue.  Their wings have nanostructures, or very very small structures, that reflect blue light.

The bottom side is brown with spots that look like eyes.  The brown provides camouflage from predators when the wings are closed.

When it’s flying the iridescent blue and brown flash making it seem like the butterfly is appearing and disappearing.  Birds and insects eat morpho butterflies.

Blue morphos eat fermented fruit.  Fermented means rotten fruit that has alcohol in it.  They eat the fruit through a proboscis, which is kind of like a straw, and is their mouth.

Blue morpho butterflies only live 3-4 weeks as butterflies because of what they eat (alcohol isn’t so good for butterflies just as it isn’t for humans).  Their entire lifespan is 115 days including when they are caterpillars.

Blue Morpho butterflies live in Mexico, Central America, and the northern parts of South America.  They have a 5-8 inch wingspan and they’re one of the biggest butterflies in the world.
