The Mission Blue is a subspecies of the Boisduval’s Blue Butterfly and has been extremely rare, with their population decreasing dramatically especially because of habitat loss. These are tiny to small-size butterflies, with the males being more attractive to the butterfly enthusiasts, having a silver-blue to violet-blue coloration (as opposed to the brown females). The flight period of the adults lasts from March to June.
