12 Types of blue butterflies

Here are 12 blue butterfly species you should look into if you’re curious about the different types of blue butterflies:

1. Blue Morpho Butterfly

Scientific Name: Morpho peleides

Blue Morpho Butterfly is a type of butterfly found in South American rainforests. With a wingspan of up to 8 inches, it is one of the world’s largest butterflies. The Blue Morpho Butterfly has been dubbed a “butterfly of kings” because you can only find it in areas far from human settlements.

This means that it is found in remote areas where there are no people rather than near civilization. The Blue Morpho Butterfly gets its name from its markings: white spots on the underside of its wings that resemble eyes—hence “peleides,” which means “eyespotted”—and its blue coloring makes it one of nature’s most beautiful creatures!

2. Cassius Blue

Scientific Name: Leptotes cassius

Cassius Blue, also known as Florida Blue, is a native Florida butterfly named after the color of the sky on a sunny day. The butterfly stands out from its surroundings due to its black body and blue wings. You can find Cassius Blue in various environments, including swamps, marshes, and fields.

During the summer, the adults are active and feed on nectar from flowers. Their caterpillars eat plant leaves and pupate underground for about two weeks before emerging as adults.

Cassius Blue butterflies are known for their voracious appetites in addition to the beautiful colors like blue on their wings!
