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.x
