Fig. 8. A tracing of a typical strike sequence from high-speed video images with the links and pivots of a four-bar linkage mechanism overlaid on the tracings. Shown from left to right, images are 0.4 ms apart with the exception of the final two images, which are 0.2 ms apart. The saddle is colored orange; v, meral-v; c, carpus; p, propodus; d, dactyl. Insets illustrate schematically the compression and release of a spring (orange) and the braced and released position of sclerite 2 (red sclerite, gray brace).
