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.

[2] The habitat consists of rocky washes, outcrops and cliffs in deserts.

[2] The larvae feed on Dudleya species, including D. cymosa, D. lanceolata and D. saxosa.

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