This dataset consists of the microsatellite genotypes, collection data, and ownership data for 1461 specimens of Bombus occidentalis. The dataset includes both recognized subspecies, Bombus occidentalis occidentalis and Bombus occidentals mckayi. The subspecies have since been elevated to species status and are currently described as Bombus occidentalis and Bombus mckayi. The specimens were collected from across the historical species range primarily between 1960 and 2020, with few specimens from earlier than 1960 and the oldest from 1904. The specimens are owned and housed by 10 different institutions, which is noted for each specimen.
