What function do halteres serve for flies and mosquitoes?

Halteres are specialized structures found in flies and mosquitoes that play a crucial role in maintaining balance during flight. These tiny, club-shaped organs are modified wings, and they vibrate rapidly as the insect flies. The primary function of halteres is to provide sensory feedback to the insect regarding its orientation and motion. By detecting changes in position and movement, halteres help the insect stabilize and control its flight path. This is essential for maneuverability, especially when flying in complex environments or avoiding obstacles. Therefore, the correct choice highlights their critical role in balance, which is essential for the effective flight of these insects.
