The butterfly genus Cycnus is now synonymized with Panthiades.

In Greek mythology, multiple characters were known as Cycnus (Ancient Greek: Κύκνος) or Cygnus. The literal meaning of the name is "swan", and accordingly most of them ended up being transformed into swans.

  • Cycnus, one of the suitors of Penelope.[5]
  • Cycnus, son of King Eredion of Achaea, who, in one version, seduced Leda and made her mother of triplets: the Dioscuri and Helen.[6] In all other sources, she had these children by Zeus who approached her in the shape of a swan (kyknos).
  • Cycnus, a blunder for Guneus in the manuscript of Hyginus' Fab. 97 (list of the Achaean leaders against Troy).

According to Pseudo-Eratosthenes and Hyginus' Poetical Astronomy, the constellation Cygnus was the stellar image of the swan Zeus had transformed into in order to seduce Leda[7] or Nemesis.[8]
