I hope you do realise that dubia and banana roaches are not in the same weight class?
Banaroaches are as big as crickets size 5 or 6, no more than that. they are good food for lateralis or some bradypodion dwarfs, not for adult panthers, you would need a 1000 for those. And they don't breed...
Hi,
I have never posted on this forum, but am not new to the parsonii's.
There is a good chance you will never see mating unless you have camera's on the cages. Look for very small black punctures on the females back and tail. They will be caused by the male and tell you if he has mounted her...
