of Pink Lady's Slipper

Cypripedium acaule (Pink Lady's Slipper)
(bees and other insects are lured to the showy and fragrant flower of this orchid by deception, as it provides neither nectar nor accessible pollen; the moth was resting on the lip of the flower; observations are from Plowright et al., Davis, Stoutamire, Barrett & Helenurm, and Wilhelm & Rericha; according to Davis, pollinators are primarily queen bumblebees)
