Life History: Pallid Dotted-Blues stay near their host plants. Males patrol around the plants all day to find females. Eggs are laid singly on flowers of the host. Caterpillars feed on flowers and fruits, and are tended by ants.

Adult Food: Nectar from Eriogonum flowers.

Range: Southeast California, Nevada, southern Utah, and northern Arizona
Conservation: Some populations are of concern because of limited habitat or threats to habitats.
NCGR: G3,G4 - . Very rare or local throughout its range or found locally in a restricted range OR Apparently secure globally, though it might be quite rare in parts of its range, especially at the periphery. Several subspecies are rank 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: Maintain habitat integrity. Monitor invasion by exotic weeds-primarily cheatgrass, and disruption by off-road vehicles.
