I agree with the classification of Flying Wyverns. For the trap question, maybe the trap is set on a specific range of weight that is to big for things such as Popo and Aptonoth, but is to small for things such as a jhen. That would seem like a good explanation except for the fact that you can trap the Deviljho in "world eater". Maybe its a very big range.
