Identification

Females are identified by contrasting yellow band on T2 (vs. more apical segments in certain other sympatric species) and orange-red tail tip (vs. white in occidentalis). Males have large eyes, a black interalar band, and basal terga extensively yellow contrasting with an orange-red tail.

Range

Southwestern United States, where best known from cismontane California

Habitat

Occurs at relatively warm and dry sites, including the inner Coast Range of California and even the margins of the Mojave Desert

Food

The Hosts section of its Discover Life species page lists known associations based on specimen records and images.

Remarks

**Listed as Endangered by the IUCN Red List of Threatened Species**

Likely undersampled in Bombus-specific studies as these focus on colder and more mesic habitats where bumble bees are more diverse
