Of course, [Jack] Vance’s brand of science fiction is atypical, to say the least. This story is among those possessing the least overtly fantastical elements of any of his work, and yet it still feels awfully fantastical. The alien culture he describes is stylish, exotic, perhaps vaguely politically anachronistic. In other words, it stands up against McCaffrey, Le Guin, or Lieber at their world-building best, possessing the same sort of fantasy sensibility one finds in his own cross-genre Dying Earth stories, though The Moon Moth is strictly free of supernatural elements.
