Fig 3. Still images from high-speed video (S2 Video) showing escape jumps of Odontomachus brunneus during interactions with the antlion, Myrmeleon carolinus.

After being attacked by an antlion (location at base of pit marked by black arrows in each frame), the trap-jaw ant (white arrows in each frame) strikes the side or center of the pit with her mandibles and propels herself away from the antlion. Time stamp indicates the time elapsed since first frame (upper left). Scale bar = 1cm.
