In a 2002 article for the journal Fremontia, Jerry Powell wrote:
"Some species feed on an array of angiosperms, or conifers, some even on both, but rarely does their diet include monocots, which mainly serve specialists with modified mandibles. The Argyrotaenia franciscana complex (Tortricidae) in coastal California is a good example; larvae have been found on a vast array of angiosperms, both woody and herbaceous, native and exotic, and occasionally on conifers. Even within populations, A. franciscana is polyphagous, recorded on 24 species of plants in 15 families at the UC Big Creek Reserve in Monterey County. These include Sequoia (coast redwood), Cupressus macrocarpa(Monterey cypress), and the succulents, Sedum (stonecrop) and Dudleya, feeding in the inflorescences. On San Miguel Island, A. franciscana insulana larvae have been found on 22 species, which is 10% of the flora, but not on monocots."
