Rhyparobia maderae are double the size of Nauphoeta cinerea and according to my book they have one of the most disgusting defensive odors. I guess they are less likely to become a pest though and that would be a plus.
So, the odor, is it defensive or is it completely dependant on humidity of the housing in your opinion? I know that the orange heads give off a pretty bad odor when I am picking out the nymphs. Anything much more than them would be pretty bad!
I can't even find anything on Princisia vanwaerebecki. Can you tell me any more about them?
