Carpenter bees (Xylocopa aruana and X. lieftincki) are so big and furry they are sometimes confused with bumblebees. The females have a bright yellow or golden thorax, and abdomens that look shiny because these are largely bare of hairs. The entire abdomen is black. They are 13-18 millimetres long. The males are yellowy-brown or olive all over, with no black on the abdomen.

The large earth bumblebee (B. terrestris), found in Tasmania, has broad bands in three colours: black, yellow (or ochre) and white. If you see one of these outside Tasmania you should report it (see our page on this bee).

The teddy bear bee (Amegilla bombiformis) is plump and furry, but is brown rather than black and yellow.
