|Paphiopedilum glanduliferum, a tropical slipper orchid that grows on limestone cliffs in New Guinea|
Many tropical Asiatic slipper orchids are pollinated by flies. The spots, bumps, hairs, carrion colors and foul odors produced by the flower attract flies seeking a food source.
Paphiopedilum glanduliferum is pollinated by hoverflies (Syrphidae) which normally lay their eggs on aphid colonies. Aphids are the food source for the larval hoverflies. The glandular hairs in the center of the flower may mimic an aphid colony.
We don't have hoverflies in the Fuqua Orchid Center. Even if we did we would prefer to hand pollinate our orchids (using a pencil, very low tech) so that we know which plant contributed the pollen and on what date. A "controlled cross," in other words.
There are always Paphiopedilum orchids in flower in the Fuqua Orchid Center. We will be happy to point them out to you.
