The Large Garden Bumblebee (meaning large bee rather than bee found in large gardens) isn't usually found in gardens. It is one of the white-tailed bees and has two yellow bands on the thorax and one on the top of its abdomen. It can be distinguished from the slightly smaller Garden Bumblebee (Bombus hortorum) by the black band on the thorax being a similar width to the two wide, yellow bands. Queen, worker and male have similar markings. The one shown above has particularly buff/ginger bands but usually the bands are more yellow.
The three bees pictured here were actually in Madeira, but the Large Garden Bumblebee is also resident in the UK.
