Xanthopan morgani praedicta Rothschild & Jordan, 1903 (African sphinx moth) In The Various Contrivances by which Orchids are Fertilized by Insects (1877), Charles Darwin described an orchid from Madagascar, Angraecum sesquepedale, whose flowers have a spur almost 12 inches long, with all the nectar at the bottom. He hypothesized that, for the plant to be fertilized, "In Madagascar there must be moths with proboscides capable of extension to a length of between ten and eleven inches! This belief of mine has been ridiculed by entomologists..." (On the Various Contrivances Whereby British and Foreign Orchids are Fertilized by Insects, and on the Good Effects of Intercrossing, 1877). Alfred Russel Wallace had also predicted its existence in Quarterly Journal of Science (1867). In 1903, this subspecies, with a 12-inch coiled tongue, was discovered as predicted.

Perkins proposed the name "funerea" to Alfred Newton, the species describer. This was not only on account of the birds somber jet black plummage, but because of "the sad fate that too probably awaits the species". Fourteen years later, in June of 1907, a collector shot and killed the last three known birds.
