Stephanomeria is a genus of North American plants also known as wirelettuce,[4] belonging to the tribe Cichorieae within the family Asteraceae.[5][6]

Stephanomeria species are used as food plants by the larvae of some Lepidoptera species including Schinia scarletina, which feeds exclusively on the genus.
