Flower-Visiting Insects
of Stiff Gentian
Gentianella quinquefolia (Stiff Gentian)
(The Large Carpenter Bee, Xylocopa virginica, perforates [prf] the base of the corollas of this plant to suck nectar and it is non-pollinating; other bees suck nectar from the flowers legitimately, and they sometimes suck nectar from the perforations of corollas that were made by Xylocopa virginica. Some bees may also collect pollen from the flowers. Observations are from Wilhelm & Rericha.)
