Valve movements outside the substrate. Spontaneous valve movements outside the substrate observed under microscope—the animal was not in the probing position and a cover glass was put on top of the ovipositor to keep it in the focal plane. Protraction of both the dorsal and the ventral valves causes dorsal curving of the ovipositor distal end. Video recorded with Leica DFC 450 C camera (5 MP) mounted on Leica DM6b microscope (Leica Microsystems). Slowed down approximately 4x.
