Stephanomeria is a genus of plants also known as wirelettuce, belonging to the family Asteraceae. The ten perennial and six annual species are restricted to western North America.[1]
Stephanomeria species are used as food plants by the larvae of some Lepidoptera species including Schinia scarletina, which feeds exclusively on the genus.
