For the second time since I have owned them, I peeked in on my U. Phantasticus pair to find my male on the ground.  From my experience with U. Sikoraes, this was always a bad sign.  It seems, however, that these guys just continue sleeping when they fall from a branch during the day.  

For whatever reason, the male’s recent favorite spot is the top corner of the enclosure hanging from a small piece of smooth bamboo.  I think slight vibrations from walking by have a tendency to knock him loose sometimes.  Needless to say, it makes me pretty scared when I see him on the ground.  I am reassured by the fact that I picked him up and put him on one of the fake leaves in the enclosure and he was very lively.
