The Matriarch appears to spawn when you run over or pass too close to a few of the small unattackable scorpion hatchlings around the area (if she hasn't been killed recently). Look for the messages telling you that a hatchling has died of pain and suffering and you'll know you're stepping on the correct mobs.
