Philotes is a genus of butterflies in the family Lycaenidae. Philotes is a monotypic genus containing only Philotes sonorensis, the Sonoran blue or stonecrop blue, found in North America in California and Baja California. The habitat consists of rocky washes, outcrops and cliffs in deserts. The wingspan is 22–25 mm. The larvae feed on Dudleya species, including D. cymosa, D. lanceolata and D. saxosa. They bore into the leaves of their host plant. Chrysalids hibernate under stones.

Taxonomy

Molecular phylogeny reconstructed a tree of the genus Pseudophilotes and identified a clade of Philotes sonorensis and Scolitantides orion as the closest relatives.
