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.
The insect fauna from the nests of birds (domestic pigeons, Columba livia ; tree sparrow, Passer montanus ; house swallow, Hirundo ruskica) were investigated in Japan. At least 15 species of insects were recorded from the pigeons nests. Black carpet beetle, Attagenus unicolor, was the most numerous insect in the nests of both pigeons and sparrow. Among these species identified in the pigeons nests, they are four species of beetles, Dermestes haemorrhoidalis, Anthrenus verbasci, Tnnodes rufescens (Dermestidae), and Aiphitobius diapeninus (Tenebrionidae) ; three species of moths, Aglossa dimidiata, Pyralis faninalis (Pyralidae), Tinea translucens (Tineidae) ; one species of booklice, Liposcelis entomophilus (Liposcelidae) and some flies, Fannia caniculanis (Muscidae) and spp. (Calliphoridae). Many lavae of T. rufescens were found from the sparrow nest. Especially, the lavae densities of T. translucensinea in the swallow nests were high.
