Strymon istapa the mallow hairstreak, mallow-scrub hairstreak, dotted hairstreak or Hewitson's hairstreak. This diurnal butterfly is a widespread species that can be found in xeric habitats throughout the southern United States, Central America, parts of the Caribbean (including Cuba and Grand Cayman), and rarely in South America.
