More than a century ago, a bluish butterfly flitted among the sand dunes of the Sunset District in San Francisco and laid its eggs on a plant known as deerweed. As the city’s development overtook the dunes and deerweed, the butterflies vanished, too. The last Xerces blue butterfly was collected in 1941 from Lobos Creek by an entomologist who would later lament that he had killed what was one of the last living members of the species.
