Fig. 10. Tarsal movements during proximal and distal slides in C. morosus and G. viridula in the `footloose' condition. In the stick insect (A proximal, B distal), a distal slide resulted in buckling, peeling off the contact area from its proximal side. In the beetle (C proximal, D distal), a distal push caused the whole pad to rotate due to its lateral instability. When fixed in all but the vertical direction (E proximal, F distal), proximal to distal peeling of the entire pad was observed. (A D) side views, (E,F) contact recorded via epi-illumination. Arrow shows distal direction.
