Pierella is a
butterflygenus from the subfamily
Satyrinae in the family
Nymphalidae found from Mexico through Central America to South America. The species of Pierella have larger hindwings than forewings, unique among butterflies. The oval green flash on the forewing is also unique. It is caused by
diffraction, the
wing scales forming a
diffraction grating.
