Ground bees

Striped with bright yellow and black like their distant cousins the yellow jackets but fuzzy like any true bee, ground bees make their nests in abandoned burrows previously belonging to such creatures as rabbits, ground squirrels, and culcarnix. They are social insects who present a hazard because of their numbers and astounding coordination. Worse, their carefully hidden nests are hard (-20) to spot; when any unfortunate being steps in or near the nest, the ground bees, warned by the vibrations, swarm out and mob the unlucky intruder. Multiple stings can cause temporary weakness and even paralysis. Like other bees, ground bees produce honey, but their underground location makes the prospect of stunning the bees with smoke and harvesting the honey rather unattractive, so any ground bees that have made their nests far from bear-infested regions (such as forests or hills) can hoard their treasure unmolested.
