Bombus crotchii is a species of bumblebee known by the common name Crotch bumblebee. It is native to California in the United States and Baja California in Mexico and has also been reported from Nevada.
This bee lives in grassland and scrub habitat types. It nests underground. Its food plants include milkweeds, dustymaidens, lupines, medics, phacelias, and sages. This bee tolerates hotter and drier habitat types than do most bumblebees.
This is an endangered species. It is thought to have declined about 67% from its historic range, at least within the United States. It was once common in the Central Valley of California, but it is now hard to find there. This region has experienced urbanization and intensive agriculture, events that are thought to have contributed to the decline of the bee .
