Mission Blue Butterflies expanding range
by Bay Nature on April 25, 2012
The endangered Mission Blue Butterfly is beginning to thrive in new areas of San Francisco, including Twin Peaks where restoration efforts are underway to bring the dazzling lepidoptera from San Bruno Mountain.
It’s habitat is restricted to only a few locations, making it prone to the harmful effects of development. Twin Peaks is one spot, along with Fort Baker and the Marin Headlands in Marin County; San Bruno and Skyline Ridge in San Mateo County; and Laurelwood Park and Sugarloaf Open Space in the city of San Mateo.
