Clearwing Butterfly, PanamaClearwing butterflies are known for their transparent wings, an adaptation that helps them vanish into their forest surroundings. Instead of relying on bright colors for warning or attraction, their see-through wings reduce visibility to predators. This species, (Ithomia diasia hippocrenis) was photographed in El Valle, Panama.
