The social insects are those insects that live in colonies or groups and exhibit cooperative behaviors. Of the options listed, the honey bee is a social insect because they live in colonies with a queen bee, worker bees, and drones. They have a complex social organization and division of labor, with each individual having a specific role to play in the colony. In contrast, mosquitoes, butterflies, grasshoppers, and cockroaches are not social insects and generally live solitary lives.
