Stephanomeria Explained

Stephanomeria is a genus of North American plants also known as wirelettuce, belonging to the tribe Cichorieae within the family Asteraceae.^{[1] [2]}

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