Certain lepidopterans (moths and butterflies) exhibit small amplitude oscillation of their antennae at constant angles during flight. Antennal movements in lepidopterans were originally hypothesized to aid in wind or gravity perception. A study performed using the hawk moth, Manduca sexta, confirmed that these tiny, antennal oscillations were actually contributing to body rotation sensation.
