Dave Bouton made the following statement

wings help in escape and finding mates, their main purpose is to disperse
the species -- spread it around --colonize greater and greater areas, put
eggs in
 new places.

Perhaps it seems too trivial, but I am not aware of any empirical evidence
that it dispersal and colonization is the main purpose of butterfly wings
(or that
wings have any purpose at all).
