#AngraecumSesquipedale / #DarwinsOrchid. This species is known for its extremely long spur, which Charles Darwin supposed must be pollinated by a moth with a very long proboscis. The moth, #XanthopanMorganiiPraedicta / #MorgansSphinxMoth, was discovered 21 years after his death. I was lucky to see the orchid at the Plant Propagation class field trip to the San Diego Zoo and later got to see two moth specimens back in the classroom. #cuyamacacollegeornamentalhorticulture #orchidmoth #darwinsmoth #angraecum #madagascarendemic #cuyamacacollege #botany #coevolution #charlesdarwin #evolution #sandiegozooplants #sandiegozooorchidhouse #orchids #orchidaceae #sphinxmoth #sphingidae #moths #lepidoptera (at San Diego Zoo) https://www.instagram.com/p/Cf0XOL-tk9d/?igshid=NGJjMDIxMWI=
