Wilwarin was one of the constellations of Arda.
Wilwarin was created by the Vala Varda. It was set in the heavens of Arda to welcome and give light to the Elves, who had just awoken in Cuiviénen.
J.R.R. Tolkien gave no description of the constellation, nor any counterpart in our modern-day constellations, but Christopher Tolkien suggested that it could be the commonly-known constellation Cassiopeia. Cassiopeia is a plausible candidate for being Wilwarin as its "W"-shape is a reasonable match to that of a butterfly.
Other versions of the legendarium
In early versions of Tolkien's notes, the name of the constellation is "Vilvarin".
Wilwarin means "butterfly" in Quenya.
