Blue coppers prefer to live in areas where species of Eriogonum are found. The larvae feed on "Eriogonum umbellatum" and "Eriogonum fasciculatum". It includes some common wildflowers such as the California buckwheat ("Eriogonum fasciculatum"). The Ben Lomond wild buckwheat ("Eriogonum nudum" var. "Lycaena heteronea" males are always patrolling between flower heads of their "Eriogonum" food plants. In Washington, the caterpillars feed on sulphur umbrella plants ("Eriogonum umbellatum"). The Eriogonum species, "Eriogonum fasciculatum", is present at the park. A variety of St. Catherine's lace buckwheat ("Eriogonum giganteum"), "Eriogonum giganteum" var. "Eriogonum crocatum" is a perennial shrub less than high by wide. One variety of this geographically limited species, "Eriogonum giganteum" var. In general, species of "Eriogonum" serve as larval host plants for "A. mormo". In the British Columbia population, the branched umbrella plant "Eriogonum pauciflorum" solely fulfills this role. The Tehachapi buckwheat ("Eriogonum callistum") is known only from the chaparral of the Tehachapis.
