Mine will eat almost every day as adults but more and more they prefer to stay burrowed for longer periods of times. I end up having to dig them up from the very bottom every week or two to feed them otherwise they have stayed down there nearly a month.

I can't afford to feed off that many dubia I feel 80 dubia a week is quick excessive if I'm reading that correctly. I feel mine are like fish they will eat no matter what till they died.
