>Jan: I have some Louisiana _U.gibba_ which is in flower right now. I tested

Wow! It seems this movement is widespread in the aquatic
Utriculariae. It would of course be fascinating to see if
Vesiculinae (e.g. _U.purpurea) or Lecticulae (_U.resupinata)
or even more "primitive" species show this, too.
Anyway, TNX for your research and for posting results.
Maybe we should inform the others out there by means of
a little paper (in CPN?).
Kind regards
