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.
