Observation notes: Emmel and Emmel have plates and descriptions in The Butterflies of Southern California. pg. 62, pg.127, I think much has changed in San Diego since the first printing of this book. San Diego's population explosion, many fires. this butterfly is probably not as secure as once thought? Applications to have this butterfly listed as endangered have been filed and time will tell.
extremely bright yellow with orange tales orange and black topside. Photo's don't tell the whole story\ a must see! its a beauty.
