McKay's Bumble Bee is a medium-sized bumble bee. It has a short head and a band of yellow hair across the thorax in front of the base of the wings. Between the wings there is a black band or a large black central spot. The tip of the abdomen is almost always white. This northern species has longer hair overall and yellow hair behind the wings and on the third segment of the abdomen, which help to tell it apart from the Western Bumble Bee.

Length: Female queens, 1.6 to 1.9 cm (0.63 to 0.75 in); Female workers, 1.1 to 1.3 cm (0.43 to 0.51 in); Males, 1.0 to 2.0 cm (0.39 to 0.79 in)
