Flower-Visiting Insects
of Whorled Pogonia
Isotria verticillata (Whorled Pogonia)
(mostly Nomadine, Halictid, and Andrenid bees pollinate the scented flowers of this orchid; flies, ants, and beetles also visited the flowers, but they were ineffective pollinators; the flowers lure insects by deception, as they provide no nectar; observations are from Mehrhoff and Pace)
