of 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, Wilhelm & Rericha, and Pace; according to Davis, pollinators are primarily queen bumblebees)
