a 11" bearded dragon can handle a few newly molted but small superworms. I have fed superworms to my dragon on and off since she was about that size and never had any problems. I still feed her some now and again for variety with her salads now.
I have fed my first bearded dragon (which I had to sell years ago...she would be 5-6 years old now...really wished my cousin called me when he didn't want to keep her anymore..at that time I would have been able to buy her back..had to sell because I was moving to another city and had to stay with friends for a couple months till I found my own place). Anyway, I never noticed undigested superworms in my dragon's poops...I could see the exoskeletons which are not digested which is normal.
Never had a dragon puke them back up...though I had one do that with silkworms but I am quite sure it was because I fed her way too many (I had left a bunch as I was going away for the weekend and thought she would just eat her fill and leave the rest, but I guess she wolfed them all down).
