Hello again!
Many butterflies today. I think this may be a Cloudless Sulphur (Phoebis sennae), but I’m not sure. Thes are quite large, and only visit the salvia greggi (Autumn sage), ignoring the other flowers in the garden. I believe you identified a similar butterfly for me several years ago, thank you!
Best wishes for a great autumn!

Sulphur, but which species?
Probably Female Cloudless Sulphur

Dear Ellen,
You are correct that this is a Sulphur in the genus
Pheobis, but we cannot say for certain which species.  Your individual does resemble the Cloudless Sulphur in this BugGuide image, but it also resembles this Orange Barred Sulphur, also pictured on BugGuide.  Unfortunately, the open-winged image you provided is lacking in critical detail.

Hello again! Thank you for your quick response. I saw the entry of the Cloudless Sulphur from Los Angeles, so beautiful.
I found this article on Orange-Barred Sulphurs (found now in California) and thought it was so interesting: http://www.monarchprogram.org/new-butterfly-species-in-the-southwest-the-orange-barred-sulfur-phoebis-philea/
I looked back at my photos and realized that, although too blurry, these show the sunlit color of the butterfly in question. It was lemon yellow, no orange that I ever spotted; I don’t know if that makes a difference or not. Gorgeous butterfly on the wing. Will keep trying to get clearer photos of the insects in our gardens.
Love your site! Thank you so much for all of the information.

Hi again Ellen,
Thanks for the update.  We believe based on the images you just submitted of a male Cloudless Sulphur, that this is a female of the species.
