The Mission Blue Butterfly (Icaricia
icarioides) can only be found in a few places
along the Pacific coast in the area of San
Francisco. They depend on just 3 species of
lupine flowers, so as development removes these
flowers and the coastal scrub environment, these
butterflies no longer have anywhere to live.
Their numbers are dwindling and they
becoming restricted to just a few park areas. I
haven't heard an estimate of their population
number exactly, but researchers say the population
is decreasing. You can check out more about them
