Psychai are the butterfly-winged goddesses/nymphs that are the progeny of Psyche. They are kin to the god Eros and his fellow Erotes. The only known psychai mentioned besides Psyche was her daughter, Hedone (Pleasure) or, to the Romans, "Voluptas". Because of them being butterfly-winged, they can often be confused with fairies or pixies, just as Eros and his Erotes can be confused with angels.
