From Wikipedia:

"Phalaenopsis (Blume 1825) is a genus of about 60 species of orchids (family Orchidaceae). The generic name means "Phalaen[a]-like" and is probably a reference to the genus Phalaena, the name given by Carolus Linnaeus to a group of large moths; the flowers of some species supposedly resemble moths in flight. For this reason, the species are sometimes called Moth orchids."
