Bombus edwardsii

Bombus melanopygus, the black-tailed bumble bee,[2] black tail bumble bee[1] or orange-rumped bumblebee,[3] is a species of bumblebee. It is native to western North America from British Columbia to California, and as far east as Idaho.[1][4]


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".[5] It feeds on many types of plants, including manzanitas, wild lilacs, 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).[6]


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.[7]
