Butterflies of San Francisco

City & San Bruno Mountain

An overview of the butterflies that can be found in the city of San Francisco, as well as nearby San Bruno Mountain. I've tried to organize it by habitat type — what you can see in your backyard, what takes a trip to a park, and what is just plain rare in San Francisco. All photos were taken by myself, though not all were taken in San Francisco. It's not a complete list of all historical possibilities within the city, but a representation of what can be expected here as of 2006.
