Bombus terrestris, the Buff-tailed Bumblebee or Large Earth Bumblebee is one of the most numerous bumblebee species in Europe. 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 5km from their nest.
