The Blue Morpho (Morpho menelaus), native to the rainforests of South America, is one of the most striking butterflies in the world. Known for its vibrant, iridescent blue wings that shimmer in the sunlight, this butterfly can grow up to 6 inches across. While its brilliant blue hue is a defense mechanism to startle predators, the underside of its wings is brown and camouflaged, helping it blend into its surroundings. The Blue Morpho thrives in tropical rainforests, feeding on rotting fruit, tree sap, and fungi, adding beauty to the jungle canopy.
