Fig. 3 in Jumping and Grasping: Universal Locking Mechanisms in Insect Legs

Fig. 3. Line drawings showing the three major types of locking mechanisms in the ventral portion of the femoro-tibial joint. Left: extended position; Right: flexed position. (A, B) TFS over Heitler's lump without conjunctiva in between (grasping legs); (C, D) GFS locked at tip of femur, no conjunctiva in between (Alticini); (E, F) GFS over Heitler's lump with conjunctiva in-between (Orthoptera); (G, H) TFS locked at tip of femur, conjunctiva in between; GFS = genuflexor sclerite, TFS = tibial flexor sclerite, distal to the left.
