In our area, its distribution largely stops at the Fall Line; few are recorded on the coastal plain (S. Droege, pers. comm.).
Description
Note lemon yellow coloration. For some reason this species' coloration tends towards bright yellow while other eastern bumbles are more subdued in their yellowness. It varies with their age (the sun fade bumbles plumage) but a nice lemon yellow usually means this species. Males have 13 rather than 12 antennal segments and the hind legs lack the pollen-carrying corbicula (bare area) on the tibia. (S. Droege, pers. comm.)

Bombus perplexus is a species of bumblebee known by the common name confusing bumblebee.[1][2] It is native to northern North America, where it occurs across Canada and into the eastern United States.[1]
The queen is 1.7 to 2.1 centimeters long and just under a centimeter wide at the abdomen. It is mostly black with areas of pale hairs. The worker female is 1.2 to 1.4 centimeters long and half a centimeter wide. It is hairier than the queen and has more yellow hairs. The abdomen is black and yellow. The male is the same size as the worker. The mandibles have reddish tips. It has white hairs on the head and legs and yellow and white hairs on the thorax.[3]
