Eriogonum

Eriogonum species are used as food plants by the larvae of some Lepidoptera (butterflies and moths). An example of a butterfly that uses this plant for food is the Lycaena heteronea. Several of these are monophagous, meaning their caterpillars only feed on this genus, sometimes just on a single taxon of Eriogonum. Wild buckwheat flowers are also an important source of food for these and other Lepidoptera. In some cases, the relationship is so close that Eriogonum and dependent Lepidoptera are in danger of coextinction.

Monophagous Lepidoptera on wild buckwheat include:

• Apodemia mormo (Mormon metalmark) – feeds exclusively on Eriogonum
  • Apodemia mormo langei (Lange's metalmark) – only known from Eriogonum nudum ssp. auriculatum
• Chionodes dammersi – feeds exclusively on Eriogonum
• Chionodes luteogeminatus – only known from Eriogonum niveum
• Euphilotes enoptes smithi (Smith's blue butterfly) – only known from Eriogonum latifolium and Eriogonum parvifolium
• Euphilotes battoides allyni (El Segundo blue butterfly) - only known from Eriogonum parvifolium

Some varieties of eriogonum, such as California buckwheat were and still are used as medicinal and food crops by Native American tribes.[3][4]
