Abdominal pumping and hemolymph pressure pulses were observed both with and without the presence of tracheal compression. Surprisingly, when tracheal compression occurred, the pressure pulses were smaller than when no compression occurred. The X-ray video shown is from the thorax of a Zophobas morio pupa, in lateral view. Video recorded at beamline 32-ID of the Advanced Photon Source, Argonne National Laboratory.
