Blooms for Bees

Buff-tailed bumblebee

Bombus terrestris

The Buff-tailed Bumblebee is one of the most common UK bumblebees, and the large queens are often the first to be seen in spring. Active colonies may be found in milder southern and urban areas during winter.

Appearance

Queens have two dirty yellow bands and a buff-coloured tail, though this can be paler.

Workers have whiter tails, often bordered by a thin line of buff hairs.

Males appear similar to workers, but the yellow collar behind their heads reaches further around their body and they have black facial hair.

In the Channel Islands all castes have pure white tails.
