Tree Bumblebee – Bombus hypnorum

Bombus hypnorum (Linnaeus, 1758)

Length queen 18 mm, worker 14 mm, male 16 mm.

The Tree Bumblebee is easily recognised by its gingery-brown thorax and black abdomen with a white tail. This is a short-tongued bumblebee. The queen may have some white hairs on her abdomen, and the male has white hairs on his face. Similar to the Common Carder Bee (Bombus pascuorum), except the Tree Bumblebee has a distinct white tail.

In its natural setting it nests in hollows of trees, but here it has taken to gardens, and particularly tit boxes.

Seen early in the year from February until July. Found in woodland, roadside verges, scrubby grasslands, parks and allotments. Often seen visiting fruit bearing plants, tree and shrubs, which make them important pollinators.

A relative newcomer to the British Isles, it was first recorded in Hampshire, England in 2001 and has steadily increased in numbers pushing northwards fringing the borders of Scotland. They have also spread rapidly eastwards, but have been slow in the west, but are now in South Wales. The bumblebee has the potential to spread throughout the whole country without any adverse affect on other species.
