Tree bumblebee (Bombus hypnorum)
One of the ‘Big 7’ widespread and abundant species, found in a wide range of habitats across the UK despite only first arriving in the country in 2001. Appears to have a distinct preference for suburbia and woodlands, perhaps partially driven by its habit of nesting in bird boxes and other manmade environments, as well as tree holes. It can now be found well into Scotland, and is widespread and abundant across England and Wales. A very distinctive species, with a completely ginger-brown thorax and a black abdomen with a white tail. Particularly in males, the first and sometimes second abdominal segments can also be brown, but there are always entirely black segments between the brown and the tail.
Melanic (all black) and semi-melanic specimens are not infrequent, but there is usually ginger discernible at the front or back of the thorax. Dark or worn specimens of the Common carder bumblebee (Bombus pascuorum) can sometimes appear similar but these never have the white tail of the Tree bumblebee.
