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 the queen's brood. In a sampling of seven "D. maculata nests", 20.9% of males were produced by workers. The percentage of males who were workers’ sons did not correlate with the time during which nests were collected or colony size. Because worker relatedness is so high in "D. maculata", workers are more related to other workers' sons than to the queen's own sons, and therefore worker policing of egg production does not occur. An explanation for the queen's near monopoly on male production is that worker production is costly and therefore reduces total colony reproduction. The cost toward worker production
