Fig. 11. Co-ordination of the legs during horizontal walking by a Empoasca.
The legs were moved in a tripod gait with the hind legs contributing to each
step. The contribution of the long hind legs imparted a sideways movement to
the body so that it oscillated about the mean forward path. Images were
captured at 1000 frames s–1; pictures at the top show three
images from one step cycle at the times indicated. Scale bar, 2 mm.
