This lore can be found by a bounty hunter on Balmorra.
While Colicoid society is not as rigidly hive-oriented as that of some insectoid species, Colicoid physiology ensures that a fertile queen will always hold a privileged position in life. Despite the fact that most Colicoid queens spend their lives being served tirelessly by their drones, workers and warriors, queens are extremely dangerous and often more than twice the size of even the largest warrior breeds. Queens are also the only Colicoids to sport a unique poison stinger that–combined with their size and strength–make them the most deadly defenders of a nest. Fortunately, a queen will usually only fight when her young are threatened.
