Vibratory communication in the humus soil

Wataru Kojima, a graduate student in our laboratory, and Dr. Takuma Takanashi (OB) of the Forest and Forest Products Research Institute revealed that pupae and larvae of a group-living Japanese rhinoceros beetle, Trypoxylus dichotoma, communicate using vibrations in their habitat, humus soil.  It was suggested that pupae generate vibrations to deter conspecific larvae, thereby preventing damage to the pupal cells, in which they molt and stretch to become adults.  Please see 'Behavioral Ecology and Sociobiology'  http://dx.doi.org/10.1007/s00265-011-1264-5 for more information.
