A continuous sampling of canopy beetles was carried out to determine variation in the abundance and the species richness of the Attelabidae and Cantharidae in a suburban mixed forest. Changes in the abundance and the species richness were monitored in three vertical strata of the forest from May to November in 1999, using yellow and blue water pan traps. The results showed significant variation in the abundance and the species richness of Attelabidae and Cantharidae between the layers, trap colors and seasons. Rare species were found in the bottom and middle layers, but were absent in the upper layer. In contrast, common species were more abundant in the upper layer than in the lower layers. The yellow traps had better trapping efficiency than the blue traps for both families, with the exception of an attelabid species, Cycnotrachelus reolofsi , which was more abundant in the blue traps. The abundance and the species richness were generally greater in spring than in summer. In spring, the abundance was consistently highest in the yellow traps in the upper layer. Season and layer were determinant factors in the species composition of the Attelabidae, while only season explained variation in species composition of the Cantharidae.
