Large Garden Bumblebee Bombus ruderatus
One of our largest bumblebee species is found only in the south of England and is scarce even there after a considerable decline through the 20th century. Widespread across this range, but never abundant where found. All three castes are similar, with a yellow-black-yellow thorax, a yellow band at the base of the abdomen, and a pure white tail.
