Bombus terrestris

Bombus terrestris, the buff-tailed bumblebee or large earth bumblebee is one of the most numerous bumblebee species in Europe. They are characterized by their white-ended abdomens. The queen is 2–2.7 cm long, while the workers are 1½–2 cm.

Apparently, such bees can navigate their way back to the nest from a distance as far away as 13 km (8 miles).
