Abstract The first record of giant axons in the central nervous system of any member of the Phasmatodea is reported. Sixteen giant fibres run through the abdominal connectives from segment 7 to segment 1 in females of C. tessulatus. The axon diameters are in the 4 to 10μm range. Action potential conduction velocities in the 5 largest axons are 2.3 to 3.2 m/s. These giant axons may mediate predator avoidance behaviour. Phasmatid giant fibres are the longest ones known from the Class Insecta and provide a useful preparation for the study of axonal physiology in insects. Copyright
