Comet orchid: Morgan's sphinx moth
When Charles Darwin studied this orchid and its 10-to-12-inch nectar tube in
the 19th century, he theorized that somewhere in the flower's native Madagascar
must exist a pollinator that has evolved a proboscis of similar length. And,
indeed, several decades after Darwin's death researchers discovered this rare
species of the Morgan's sphinx moth with its exceptionally long proboscis.
