Abstract: The Osmanthus fragrans(Thunb.)Lour.(Oleaceae)flower visiting insect species and foraging behavior have important significance on the study of the pollination biology and breeding system evolution.Their visiting frequency,visiting duration and behavior were observed and recorded. The results are as follows: the flowers are visited by 18 species of insects which belong to Hymenoptera, Lepidoptera,Diptera, Coleoptera and Hemiptera. And there are 7 kinds of insects belonging to Lepidoptera, 6 kinds of insects belonging to Hymenoptera,3 kinds of insects belonging to Diptera, 1 kind of insects belonging to Coleoptera and 1 kind of insects belonging to Hemiptera. The main pollinators are bees and flies,because they have high visiting frequency and large number.The peak visiting frequency appeared in full bloom.The daily activities of the main pollinators appear single-peak type and double-peak type, which indicating a comple-mentary relationship among the pollinators. The visiting frequency and landing time of main pollinating insects showed negative correlation.
