Starspot rotation rates versus activity cycle phase: Butterfly diagrams of Kepler starts are unlike that of the Sun

Context. During the solar magnetic activity cycle the emergence latitudes of sunspots change, leading to the well-known butterfly diagram. This phenomenon is poorly understood for other stars since starspot latitudes are generally unknown. The related changes in starspot rotation rates caused by latitudinal differential rotation can, however, be measured.
