The hibernation adults of the red flour beetle, Triboliuin castaneum (HERBST) have been many times found under the barks of Keyaki, Zelkova serrata MAKINO in field since 1991. Several tens of the beetle were found on per tree, while a few of individuals coexisted with other native species of beetles on a piece of bark. These adults had been living till next spring and dispersed after the termination of overwintering. One adult flying at the borders of woods near the hibernating site was caught in May, 1998. It is presumed that the wild population of red flour beetle exists in Japan.
