A bumblebee (Bombus argillaceus) pollinating silver sage (Salvia argentea). The stigma of the flower touch on the bumblebee's thorax that is full of pollen from the previous flowers it has visited. At the same time, the hairs of the thorax gather pollen from the anther. This species of bumblebee has such a long proboscide as it needs to be able to reach the nectar of Lamiaceae flowers.
