Table 1. Species
diversity of floral resources and the number of flowering species in the
fixed plots in each census. As an index of species diversity,
Shannon-Wiener’s H’ values are shown. In total, flowering of 81
species was observed in the plots throughout the survey periods and was
classified into bee-visited (N = 21), fly-visited (N =
53), and unclear (N = 7) according to their floral visitors.
