We surveyed flower visitation pattern of bees and wasps in Nara and Kyoto in 2011 and 2012. We observed five species of Apidae and eight species of Vespidae at the flowers of 81 species of plants in 38 families. We measured color for bee, brightness for bee, shape (dish to bowl, bell or funnel, brush, flag, tube), size, nectar guide, nectar volume, and nectar concentration as floral characters. Wasps visited green flowers more frequently than bees. Furthermore, the visitation pattern of wasps was influenced by interactions between flower shape and size. Apis mellifera visited green flowers more frequently than Apis cerana japonica. Bumblebees and Tetralonia nipponensis were tended to visit flowers with high concentration and much nectar than the other species in 2012. This was because these bees could feed on nectar of azalea easily by their long tongue.
