Vespoidea is a superfamily within the order Hymenoptera, which includes various wasps, hornets, and yellowjackets. These insects are characterized by their narrow waists and often have a stinger, which they use for defense. Many species within this group are social, living in colonies with a queen, workers, and drones. Members of Vespoidea play important roles in ecosystems, such as pollination and pest control. They are found in diverse habitats worldwide, from forests to urban areas. Some species are known for their aggressive behavior, especially when defending their nests, while others are more solitary and less harmful to humans.
