The Riodinidae (or Metalmarks) are a family of butterflies. While the Riodinidae are now considered a distinct family within the superfamily Papilionoidea, in the past they have been grouped as a subfamily of the Lycaenidae. The common name Metalmark refers to the small metalic-looking spots commonly found on their wings. There are approximately 1,000 species of Metalmark butterflies in the world.
