Hymenoptera is an order of insects that includes familiar species like bees, wasps, and ants. These insects are known for their two pairs of wings and a distinctive body structure, which often features a narrow waist. Many Hymenoptera play crucial roles in ecosystems, such as pollinating plants and controlling pest populations. Some Hymenoptera are social insects, living in large colonies with complex social structures. For example, honeybees work together to build hives, gather food, and care for their young. Others, like certain wasps, are solitary and hunt for food on their own. Overall, Hymenoptera are vital to both nature and agriculture.
