A Loosdrecht allegorical vase by Duvivier

Not long ago several pictures of this very unusual Loosdrecht vase (auctioned in England in 2014) were sent to me by its present owner. A rare and curious vase, indeed, for its painted decoration, done by Fidelle Duvivier. We see a draped putto or child holding up a ribbon from which a bat hangs with its wings extended. The vase is unmistakably neoclassical in style, but what is the bat meant to signify in this decoration?
