Usually, there is not much left to harvest for bees by mid-October here, but the colorful Tropaeolum majus (garden nasturtium or monks cress) blossoms until the first seriously frosty night.
Some of our honeybees are still breeding winter bees, who live until spring, much longer than worker bees in summer. So workers still search for pollen to feed the brood:
There's a litte pollen left here on Tropaeolum stamen. The lower petals "brush" the visitors to increase the chance of pollination when they reach further in for the nectar.
Brushing the pollen off the stamen with front legs, holding it with middle legs:
Stowing it for transport:
Maybe it is easier to tell the legs apart in a crop (50% pixel-wise):

The detail shots are part of my 1:1 effort (24mm picture height). All taken using my DFA 100mm WR on a K-1, at f/16 for the bee pictures, using a flash with a large ring-diffuser.
