A bit more info for those who are curious: All 30 butterflies on the poster live on San Bruno Mountain, and are confirmed by recorded sightings on iNaturalist and noted in the wildlife section of the book The Flora of San Bruno Mountains by Elizabeth McClintock et al. The native host plants (also found on the mountain) of each caterpillar were researched through books and online sources. Photos are public domain and free of copyright, or taken by SBMW on the mountain. If you have further questions about the design or research process behind the poster, please email ariel@mountainwatch.org
