Bombus melanopygus, the black-tailed bumble bee,[2] black tail bumble bee[1] or orange-rumped bumblebee,[3] is a species of bumblebee native to western North America.

This bee is widely distributed across western North America, from the Pacific to the Rocky Mountains, and from Alaska to Baja California.[4][5]

There are two forms of the black-tailed bumblebee:[4]

  • Red form (“red butts,” Bombus melanopygus melanopygus) found primarily in higher latitudes of Oregon and points north, and in the Mountain West
  • Dark color form (Bombus melanopygus edwardsii) is most common in California and southern Oregon

(The second and third abdominal segments are red in northern populations and black in southern; individuals with black segments were previously known as Bombus edwardsii, a separate species. Genetic analyses support the conclusion that the two forms are the same species, with B. edwardsii as a synonym.[6])

This bumblebee can utilize a number of habitat types, including agricultural and urban areas. It is "one of the few bumblebees still found regularly in San Francisco".[7] It feeds on many types of plants, including manzanitas, Ceanothus, goldenbushes, wild buckwheats, lupines, penstemons, rhododendrons, willows, sages, and clovers. It nests underground or aboveground in structures.[1]

This species is a host to the zombie fly (Apocephalus borealis).[8]
