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 colonies have been observed in central Pennsylvania as late as mid-October. The colony is founded by a single overwintered, inseminated queen. She rears the first generation of workers on her own until they are functional. Colonies pass through the foundation over an average period of 23–24 days. After the queen lays her eggs, it takes 6 days for them to hatch. They grow as larvae for eight days. It takes them an additional 9–10 days to mature into adult workers. During the ergonomic stage, the colony's activities are concerned with cell building and worker production. The queen devotes herself entirely
