In this study we investigated floral biology and flower‐visiting insect fauna in natural populations of six dioecious species of Lindera (Lauraceae) in Kyoto, Japan. Flowers of the Lindera species were similar in structure and floral attractants, and were visited by a wide range of insects. Although typical of generalist‐pollinated flowers, interspecific differences were found in flower‐visitor composition. All species of Lindera flowered early in the growing season, from February to May. However, peak flowering periods of different species of Lindera were staggered. Slight interspecific and intersexual divergence of flowering phenologies may reduce interspecific cross‐pollination. Results of this study suggest that interspecific segregation of pollinators was associated with seasonal divergence of phenological patterns, rather than character displacement of floral attractants.
