Beetle samples captured by traps were compared with those captured manually on flowers in a beech forest in Central Japan. Plastic traps (Sankei Chemical Co., Ltd.) equipped with benzyl acetate were set up from the 2nd of June to the 8th of September 1994. and all beetles captured were collected every week. Beetles were also captured on wild flowers blooming along the forest road. The traps captured 21,650 individuals of 169 species in 37 families. On the other hand. 971 individuals of 77 species in 19 families were captured on the flowers. All of the families and 57 (74%) species of the beetles captured on the flowers were also captured by the traps; all of the species with more than five individuals captured on the flowers were also trapped, except for one species. The present trap system is considered to be useful for faunal monitoring of flower-visiting Coleoptera. because the beetle fauna found on wild flowers was virtually covered by the trap capture.
