Fun facts
Its other name, two-form bumblebee, is a mistake. Scientists thought it came in a red-tailed and a black-tailed form, but the black-tailed ones turned out to be a different species.
Scientists only proved in 2020 that the two look-alike bumblebees are really separate species.
Its queens are bigger than the workers, up to about 19 millimetres long.
The pollen baskets on its back legs are orange-brown.
