Hair plates are tight bundles of tactile hairs used for proprioception and mechanosensation in insects. They are often located at folds in the cuticle, so that they are deflected when the insect moves a joint relative to another. When they occur at the base of the antenna, such as in cockroaches, they may be used for mechanosensation by sensing the deflections of the antenna.
