English: A red-tailed bumblebee (Swedishː stenhumla) or bombus lapidarius, a female worker, collecting nectar and pollen on chives. On its rear legs you can see pollen baskets (or “corbicula”), where it stashes loads of pollen to carry back to the nest. The picture was taken in a garden in the southern part of the Stockholm Municipality, Sweden, by Lake Mälaren, the third-largest freshwater lake in Sweden (after Vänern and Vättern).
