User blog comment:Lord Loss/Monster Hunter Theory... Blog/@comment-4212769-20120601200745

I have a theory about the Narga Sub:

It is the opposite gender of normal Narga. They hunt at opposite day times; means Narga at night and Narga Sub at day. So they can raise their children with one parent at the nest and the other on the hunt. The Green Narga needs more agility because of the more rivals out there. About the colors I don't need to say that they have great camouflage effect.

They live in the same areas so I think this is probably true. The Green Narga is not at Minnegard because he wasn't found there yet or because it's only at Moga.
