Honeybees Apis cerana japonica shook their own body to threaten a wasp Vespa simillima xanthoptera, when it approached to their nest which was built in the hollow of a tree. This behavior propagated in waves among the population. This propagation was also observed when a wasp did not appear (3rd propagation). Therefore, this threatening behavior was considered to be released by not only a wasp approaching but also the same behavior of an adjacent individual. By acquiring the latter releaser individually, the population of honeybees is able to percept the wasp approaching more sensitively, and transmit threatening signal more strongly.
