The air-floating beetle community was surveyed by flight intercept traps (FIT) for each of four stations in the garden of the Imperial Palace, the center of Tokyo, Japan. Three hundred and ninety-three species, 13,838 specimens in 61 families were collected in total, 45 species of which are going to be recorded from the Imperial Palace for the first time. The species diversities and their dynamics of the community of the superfamily Staphylinoidea and that of the other beetles were analysed by Estimates (Corwell, 2005), some diversity indices (Shanon-Wiener function H', J' and H'N), and similarity indices (Jaccard's CC, NSC, Pianka's α). As the result, the following three were pointed. 1) For one station the potential number of species (ICE) were estimated about 76 for Staphylinoidea and about 248 for the other beetles on average, however their percentages of clarification (Sobs/ICE) are low, about 70%. 2) The species diversity was generally high from March to July with large deviation, successively decreased in September, and very low in October to November. 3) Among the stations 1 to 4, the air-floating beetle fauna of St.4 was distinctly different from the other stations, probably because waterside beetle habitat was included only in St.4.

In 2000 to 2003, the terrestrial staphylinoid fauna was quantitatively surveyed at nine stations (TK01-TK09) six times a year for each in the garden of the Imperial Palace, Tokyo, Japan. Each staphylinoid sample was extracted by Tullgren funnel from leaf litter and humus of five quadrats each sized 1m×1m. Sixty-two species of four families were recognized, 13 species of them being recorded for the first time from the Imperial Palace. Species diversity and similarity of six communities were analyzed by three diversity indices (Shanon-Weaner function H', Pielou's index of equitability J' and total diversity H'N) and three similarity indices (Jaccard's coefficient of community CC, Nomura-Simpson's coefficient NSC and Pianka's overlap index α). In the comparison of species diversity, TK03 was significantly low in H' and H'N and the other five were not different. In TK01 to TK03 surveyed in 2000-2001, the diversity was high in January to May, in a low level in July, and recovered in September; on the other hand, it decreased more or less in June to October in TK07 to TK09 (2002-2003). As to the similarity of species component, TK07 harbored many species completely covering the faunas of TK01, TK02 and TK03. A significant difference of TK09 in overlap similarity was indicated in an analysis by Pianka's α.
