Adult Food: Nectar from flowers of wild lilac (Ceanothus) and other plants.

Conservation: Because of its small range and susceptibility to fire, this butterfly is of a high conservation priority.
NCGR: T1 - Critically imperiled because of extreme rarity (5 or fewer occurrences, or very few remaining individuals), or because of some factor of its biology making it especially vulnerable to extinction. (Critically endangered throughout its range).
Management Needs: Inventory and monitor population, manage fire as carefully as possible..
