Using floral form to generate hypotheses regarding pollination ecology was most famously advanced by Darwin, who predicted in 1862 that the long-spurred Angraecum
sesquipedale orchid would be visited by a similarly long-tongued moth, a hypothesis proven correct 130 y later (Wasserthal, 1997).

Glomeremus orchidophilus - a raspy cricket - made the top 10 list for its distinction of being the only pollinator of the rare and endangered orchid Angraecum
cadetii on RAeunion in the Mascarene Archipelago in the Indian Ocean.
A comparable and frequently cited, long-proboscid taxon--but in the Lepidoptera--is the hawk moth Xanthopan morgani praedicta Rothschild & Jordan, 1903 from Madagascar (proboscis length about 25 cm), which pollinates the long-spurred Madagascan star orchid Angraecum
The star orchid of Madagascar, Angraecum
sesquipedale Thou., is pollinated by a single hawkmoth, Xanthopan morganii predicta Walker (Wasserthal, 1997; Nilsson, 1988) whose existence was famously predicted by Darwin (1862).
They wanted to know how an orchid called Angraecum
cadetii becomes pollinated, so they aimed their night-vision cameras at the flowers and hit the "record" button.
In January 1862, he received some flowers of Angraecum
sesquipedale (the Madagascar star orchid or Darwin's orchid), a native of Madagascar.
