I've noticed most Roaches with wings, they seem to be able to glide/flutter. My dubia males seem to be quite a bit more talented than the Lobsters though.

I was told the same thing, non-glass climbers, no flying. It's a bit of a manipulation on words though. By "flying" they mean dubia can not fly straight up or for an extended amount of time. They more or less glide down to the floor....or in your dogs mouth...whichever.
