Bee sting most aggressive stinging insects are vespid wasps (including bald-faced hornets and other yellowjackets) and hornets (especially the Asian giant hornet). All of these insects aggressively defend their nests. Although for most people a bee sting is painful but otherwise relatively harmless, in people with insect sting allergy, stings may trigger a dangerous anaphylactic reaction that is potentially deadly. Additionally, honey bee stings release pheromones that prompt other nearby bees to attack. A honey bee that is away from the hive foraging for nectar or pollen will rarely sting, except when stepped on or roughly handled. Honey bees will actively seek
Bald-faced hornet and colonies whose work force diminishes too early in the colony's life cycle will suffer a greater overall total loss in reproductives. A colony is divided into sterile males, female workers and the queen. All females are born with reproductive capacities. Caste systems are determined by larval feeding regime. G.T. Felippotti examined caste distribution amongst females in five small cell colonies and six large cell colonies. Small cell colonies had one queen and 17–21 female workers. Large cell colonies had 2–6 queens and 10–52 workers. Morphological comparisons revealed that queens are always larger than workers in the same colonies. Cuticular
