There are plants on the planet that are best-pollinated by one specific insect. This is true for orchids in the genus Catasetum, which requires the Euglossine or orchid bee to help carry pollen between the neotropical Catasetum’s male and female flowering plants.
“Bees soon learn that the male flowers are rather unpleasant places to visit so they set off in search of a meal that doesn’t pummel them. This is quite possibly why the flowers of the individual sexes look so different from one another. As the bees visit the female flowers, the pollen sacs on their back slip into a perfect groove and thus pollination is achieved.”
The second half of the clip shares how Madagascar‘s comet orchid, also ocalled Darwin’s orchid in the in the genus Angraecum, is pollinated by the Morgan’s sphinx moth. The insect’s unusually long proboscis makes it the only pollinator capable of reaching down the comet orchid’s long spur—”27–43 cm (10.6–16.9 in) from its tip to the tip of the flower’s lip”—to reach nectar.
