My killer bee has a bit of that "spider wobble". When I first got him, he would miss striking the f/t meal and I blamed the "wobble". I started running the f/t meal in a plastic bag under running hot water for about a minute or so before offering it to him on tongs. Now he rarely ever misses and if he does he comes right back at it.

Also if she is eating by leaving it in her cage overnight, she is still eating.
