What is the function of halteres in Diptera?

Halteres in Diptera function as gyroscopic balance organs that stabilize flight. They are modified hindwings with knob-like ends packed with mechanosensory receptors. When a fly tilts or spins, inertial forces cause the haltere knob to bend slightly, and the resulting sensory signals report angular velocity to the nervous system. The brain uses this feedback to adjust wing motion in real time, allowing precise control, quick maneuvers, and stability during flight. They are not used for storing food, respiration, or sound production, which are handled by other structures in the insect.
