Buff-tailed bumblebee

Description:

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 5 km from their nest. The first bumblebees to be seen in spring are the queens – the queen is the only bumblebee to hibernate through the winter. The queen is much bigger than the workers, which appear later. As soon as the queen has found some nectar, to replenish her energy reserves, she starts looking for a suitable site to build her nest.
