The olethreutine moth Epinotia kasloana known to utilize jojoba (Simmondsia chinensis ) and species of Ceanothus as host plants. Included here are observations on the life history of this moth on sylvatic jojoba is southern California and Arizona. Larvae feed on male flowers, developing fruits and leaves during spring. There are five larval instars. After feeding, fifth instar larvae drop to the ground and construct a hibernaculum in which they remain throughout the summer months. Pupation occurs in fall and adults are active in late fall and early winter. Oviposition occurs primarily on leaves, and is more common on male plants.
