双翅目昆虫（真正的苍蝇）有一对复杂的平衡器官，称为Halteres，它是从后翅进化而来的，Halteres对身体角旋转产生的科里奥利力敏感，并在飞行过程中调节校正反射，就像空气动力学功能的前翅一样，Halteres在飞行过程中跳动，并配备有自己的一套控制肌肉。结果表明，运动神经元支配的肌肉的haltere收到强烈的兴奋性输入方向敏感的视觉中间神经元。果蝇视觉引导的飞行动作可能部分由硬连线平衡反射的传出调制介导。
Dipterous insects (the true flies) have a sophisticated pair of equilibrium organs called halteres that evolved from hind wings, The halteres are sensitive to Coriolis forces that result from angular rotations of the body and mediate corrective reflexes during flight, Like the aerodynamically functional fore wings, the halteres beat during flight and are equipped with their own set of control muscles. It is shown that motoneurons innervating muscles of the haltere receive strong excitatory input from directionally sensitive visual interneurons. Visually guided flight maneuvers of flies may be mediated in part by efferent modulation of hard-wired equilibrium reflexes.
