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.
