I've not done the Hive either, so take this with a grain of salt, but I'm pretty sure it's just NE of Neamsog Bunker. If you can picture the long slope leading up to the Aukfruit areas and the plateau there, there's a dungeon near the foot of the slope on your right (east) as you look up the slope. It's got a bunch of wasp-thingies outside and at least a few of the quests are obtained at Neamsog.
If that's not the place then... what IS that place?
