Bombus cockerelli, Cockerell's bumblebee, is a yellow and black bumblebee known only from fewer than 30 specimens, collected at a few high-altitude (over 6,500 ft or 2,000 m) localities in the White Mountains of New Mexico, all within an area of less than 300 square miles (780 km2), giving it the smallest range of any of the ~250 species of bumblebees in the world.[1][2]
Bombus cockerelli is a typical bumblebee in appearance, with queens 15–20 mm (0.6–0.8 in) long, and distinctly smaller workers. The queens and workers are black on the head, with a few pale yellow hairs. The anterior and posterior thorax and the two basal and two terminal abdominal segments are yellow, while abdominal segments 3 and 4 are black.[3] Males are unknown.
Another species of bumblebee, Bombus balteatus, known to occur at high altitudes in Colorado, is similar to B. cockerelli,[4] but B. cockerelli has a shorter head, numerous intermixed black hairs on the anterior thorax, and the abdominal apex is yellow rather than rust-tinted.
The bee was first described in 1913, based on six specimens collected near the Rio Ruidoso in New Mexico. Between 1956 and 2011, not even one was seen.[5] For a time, this bee was believed to be just a subspecies and not a full species. However, given access to fresh specimens whose genetic material can be analyzed, it is expected that it will now be possible to determine whether it is a true species.[1]
Despite how rarely it has been seen, the bee is not believed to be endangered or threatened, because its entire range is in U.S. National Forest and tribal lands.[1]
Nothing is known regarding the biology of this species, other than some specimens having been collected on thistle flowers.[1]

Bombus cockerelli[2][3] är en biart som beskrevs av Franklin 1913. Den ingår i släktet humlor och familjen långtungebin.[4][5] Inga underarter finns listade.[4]
Artens taxonomiska ställning är omstridd; vissa auktoriteter betraktar den som en synonym till Bombus vagans[1].
Bombus cockerelli har övervägande gul mellankropp, tergiterna (ovansidans bakkroppssegment, nummer ett längst fram) nummer ett, två och fem ljusgula, de övriga svarta utan spår av gult utom på den yttersta sidobehåringen.[6].
Arten förefaller vistas i täta skogar. Hanar har ännu ej påträffats.[7] Humlan har påträffats på nicktistel[6].
Arten förekommer endast på ett omkring 777 km2 stort område i New Mexico i USA, det minsta område över huvud taget för någon humleart.[7] Arten är mycket sällsynt; mellan 1913 och 1956 hade endast 23 individer påträffats. 2011 upptäcktes ytterligare 3;[8] fram till 2013 har totalt 34 individer upptäckts[7].
