Flower-Visiting Insects
of Showy Lady's Slipper


Cypripedium reginae (Showy Lady's Slipper)
(Bees and other insects are lured to the flower of this orchid by deception, as it provides neither nectar nor accessible pollen. According to Guignard, bees are the only effective pollinators. However, Vogt has claimed that other insects, including Syrphid flies and Scarab beetles, are sometimes effective pollinators. The skippers were ineffective at pollination because they entered the lip of the flower and became trapped there. Observations are from Guignard, Stoutamire, and Vogt.)
