Plataspidae, commonly known as shield bugs or stink bugs, are a family of insects belonging to the order Hemiptera. They are characterized by their shield-shaped bodies and distinctive scent glands that emit a foul odor when disturbed. These insects are typically found in temperate and tropical regions, and they feed on plant sap using their piercing-sucking mouthparts. Plataspidae play important roles in ecosystems as both pests and beneficial predators of other insects.
