Bees respond to gravitational and centrifugal stimulation by characteristic movements and postures of their antennae. Depending upon the direction of motion in relation to the bee's body, one or both antennae point against the direction of movement. Together with the antennal postures, definite postures of the abdomen can be observed. Free running bees also exhibit postural responses of the antennae which are correlated with the direction of progression under the influence of centrifugal force. Removal of the antennae does not eliminate postural responses of the body. In several other insects similar postural responses can be observed, while in certain forms they do not appear.
