I had never seen an Echo Blue butterfly before, but look who visited our garden yesterday afternoon and lingered for about half an hour! It rested in the sun on an evergreen hedge after visiting our native plant garden.
The Echo Blue Celastrina ladon echo, also known as the Spring Azure, is said to be common in the Bay Area. They visit many kinds of flowers, and some of their host plants are in the Ceanothus species.
I wonder if there are Echo Blue larvae developing on our Ray Hartman Ceanothus shrub, which is thriving in the native garden.
