To celebrate the 100th post, I chose to post about the moth which Charles Darwin predicted after observing the flower of the Madagascan orchid Angraecum sesquipedale in 1862. The specific epithet translates from Latin to “one and a half feet”, referring to the “astonishing length” of the spur of the flower. He believed that a flower with a spur so long would have a pollinator with an equally long proboscis. It was not until 1903 that the pollinator, Xanthopan morgani,was described, some 41 years later.

Angraecum stella-africae, known from only a few locations in southern Malawi, northern South Africa and Zimbabwe. Until fairly recently, the last known record of this species in Zimbabwe was from 1977 and was thought to be extinct in that area. However, a small but healthy population was discovered in the Vumba Mountains in 2004, where this individual was photographed in situ. Photograph and information found on Bart Wursten’s website, Flora of Zimbabwe.
