Jean Claessens, the maker of this video, writes about it:
In Garmisch-Partenkirchen (Germany) I had the chance to observe the pollination of the orchid Spiranthes spiralis by a small solitary bee, Halictus simplex. This bee has an ingenious, articulated tongue that enables this small bee to reach the nectar hidden in the flower of Spiranthes spiralis.
Flower lures pollinators with smell of honeybee fear. Trick deceives carnivorous flies with promise of bogus meal: here.
