Video of male postcopulatory tremulation of the katydid, Nesoecia nigrispina (Orthoptera, Pseudophyllinae)

<p>After copulation, the female does not emit signals, and the male continues to produce rhythmic series of vibrations. From time to time, the male produces a series of oscillations of extremely high-amplitude single blows of the body against the substrate during which the insect literally jumps in place (see in the end of the video).</p> <p>Recordings were performed using a Nikon 1J4 video camera without an infrared filter under the light of an Orient SAL-130C infrared illuminator.</p> <p>&nbsp;</p>
