Movie 3

Demonstration of the in- out scanning motion of the wasp ovipositor. The tip is exerted beyond the sheath and then retracted; this motion could help the sensilla-rich tip to perceive volatiles and other chemical cues even when the ovipositor continues to remain covered by the sheath prior to oviposition (during oviposition, the sheath remains outside the fig and the ovipositor gets inserted into the syconium).
