are short. Females (queens and workers) have a predominantly black abdomen with a yellow collar, the first and sometimes second terga yellow, and a white tail. The face is black, occasionally with a patch of yellow fur on the top. Males are similar, but with more yellow; the yellow collar continues on the ventral side, the two first terga are always yellow, and much more yellow fur is found on the face. However, darker forms of the females are seen, as well as forms (sometimes considered subspecies) that differ in the amount of yellow in the fur, and with brownish hairs on the white tail. Among these are ''B. j. hebridensis'' (which is endemic

Ecology
The heath humble-bee is found in gardens and meadows, as well as on heath and moorland. The bumblebee visits various food sources, such as clover

, bird's-foot trefoil, cowberry, thistles, and many others.
The nest, which at most can contain 50 to 120 workers, can be situated both above and under ground. When the climate permits, as in southern England, this species can have two broods a season. A study in northern Sweden shows the males, when patrolling for young queens, do so at tree-top level, marking twigs and leaves with pheromones to attract the queens.
