Family Name: Orchidaceae
Native to: Madagascar
The Angraecum species currently on display is an Angraecum sesquipedale, commonly known as the Darwin orchid. Charles Darwin was the first to hypothesize that the flower’s pollinator was a moth with a very long proboscis. His prediction was not verified until 20 years after Darwin’s death when the large sphinx moth, Xanthopan morganii praedicta, was discovered.
Nectar is stored at the bottom of the flower’s spur, which looks like a long tail. In order to reach the nectar, the moth must have a very long proboscis. While the moth attempts to get the nectar, other parts of its body pick up or deliver pollen to the orchid’s reproductive column. Many species of Angraecum are critically endangered due to habitat loss and over-collection for trade. The species name sesquipedale is Latin for ‘one and a half feet’, which refers to the length of the spur
