Abstract

A range of beetle species are associated with plants and many of them reside primarily in flowers; of these Nitidulidae possess a large share. Beetles which thrive upon angiosperms exhibited a rapid rate of speciation as compared to others with different feeding habits. Hence, beetles and angiosperms have co-evolved and influenced each others’ evolution for better survival. Some flower-visiting beetles have developed special features for floral diet and other purposes like pollination, shelter, reproduction, etc. Likewise, certain flowers also have adapted structurally and physiologically to attract beetles for pollination which include pollen, nectar, floral heat etc. Although beetles are found to be amongst the pioneer flower visitors, they are not as efficient pollinator as bee and butterfly. However, they have been found to be chief pollinators for a few plant families like Magnoliaceae, Annonaceae and Palmae. Several sap beetles have been encountered in floral parts in West Bengal, Assam, Uttar Pradesh, Karnataka and Tripura. Nature of relationships of those beetles with inflorescence and flowers were examined. None of them is yet found to be a true pollinator.
