Like all such dragons, Megalarmolagrax is a nasty piece of work.  Utterly cruel, deceitful, conniving  and manipulative.  To him, all other life forms pawns, prey, or both.  He lives in the darkest, densest part of the forest, and patrols the area, flying above the canopy, on a roughly monthly basis, looking for potential food, travellers or adventurers, or anything else useful that may have entered the area.

If he sees adventurers, he is likely to check them out to assess their actual power.  If he has no reason to think that they could be a threat to him (and usually, they can't), he will likely terrorize them, swooping down and then away, striking and then flying off, using his poisonous breath, in general toying with them cat-and-mouse style before finally killing them off when he gets bored.  

If he thinks they may have useful information (what's going on, who are they, etc), he may interrogate them either by intimidation of magic or both.  If he considers them a threat, he is likely to use magic, or stalk them, waiting until they are vulnerable.  All typical green dragon tactics.
