buff-tailed bumblebee

The queen is 2–2.7 cm long, while the workers are 1½–2 cm. The latter are characterized by their white-ended abdomens and look (apart from their yellowish bands being darker in direct comparison) just like those of the white-tailed bumblebee, B. lucorum, a close relative. The queens of B. terrestris have the namesake buff-white abdomen ("tail") tip; this area is white like in the workers in B. lucorum. Such bees can navigate their way back to the nest from a distance as far away as 13 kilometres (8.1 mi), although most forage within 5 km from their nest
