Inciting Pheromone (Ex) If a melee attack reduces a howler wasp to 0 or fewer hit points, or if the wasp takes a critical hit from a melee attack, it can attempt to douse its foe with a pheromone (+3 melee touch). The wasp uses this ability as an immediate action before resolving the effect of the damage.

The pheromone draws other howler wasps to the target, inciting them into a fearsome rage. All howler wasps within 60 feet of a creature doused with the pheromone gain a +1 bonus on attack rolls and a +2 bonus on damage rolls against the doused creature. Howler wasps detect the doused creature as if they had blindsense. The pheromone's effects last for 10 minutes, though a doused creature can wash the substance off by submerging in water.

The colony's queen, like that of a mundane wasp nest, is responsible for laying eggs. Male howler wasps crowd about her at all times.
