Rhetus periande are found in most of Central and South America, ranging from Mexico through to Brazil and Argentina.
    Their preferred terrain is around forest edges and along riverbanks.
   They have an extremely fast flight.
   The male has hindwings with curved, broad tails.     The wings are black on the dorsal side with large blue inner parts and red spots on the hindwings.         The ventral side is brown with longitudinal white stripes and red lines at the inner margins of the forewings and red spots at the base of the hindwing tails. 
      When feeding, the adults fly from flower to flower, compelled by the search for pollen to consume.
   They are attracted to the bright colors and distinctive shapes of flowers, thus becoming a pollinator in its search for food.
   Potential predators include spiders, birds and bats.
