Habitat
This subspecies of butterfly faces declining habitat which has contributed to its migration onto the list of federally threatened species. Like other endangered and threatened species of butterfly in and around the Bay Area the checkerspot is faced with rapid human development of areas once considered prime habitat. Development and the proliferation of invasive species, exotic non-natives that naturalize in the area, are two of the three most grave threats to this and several other species of butterfly. The threat to the butterfly that is likely greatest comes from the increasing emission of nitrogen in California.
