The Role of Beetle Marks and Flower Colour on Visitation by Monkey Beetles (Hopliini) in the Greater Cape Floral Region, South Africa Nänni, Ingrid Background and Aims: A deviation from the classical beetle pollination syndrome of dull-coloured flowers with an<br />unpleasant scent is found in the Greater Cape Floral Region of South Africa. Here, monkey beetles (Scarabaeidae)<br />visit brightly coloured, odourless flowers with conspicuous dark spots and centres (beetle marks). The role of flower<br />colour and markings in attracting monkey beetles is still poorly understood.<br />Methods: Artificial model flowers with different marking patterns were used to test the effect of beetle marks on<br />visitation by monkey beetles. To test whether monkey beetles are conditioned to the colour of the local matrix<br />species, model flowers of different colours were placed in populations of three differently coloured species of<br />Iridaceae.<br />Key Results: Among all three matrix species the presence of dark markings of some kind (either centres or spots)<br />increased visitation rates but the different matrix species differed in whether the effect was due to a dark centre or to dark spots. Monkey beetles were not conditioned for the colour of the matrix species: model colour was not significant in the Hesperantha vaginata and in the Romulea monadelpha matrices, whereas yellow model flowers were<br />preferred over orange ones in the orange-flowered Sparaxis elegans matrix.<br />Conclusions: This study is the first to demonstrate that beetle marks attract pollinating monkey beetles in the<br />Greater Cape Floral Region. In contrast to plants with the classical beetle pollination syndrome that use floral<br />scent as the most important attractant of pollinating beetles, plants with the monkey beetle pollination syndrome<br />rely on visual signals, and, in some areas at least, monkey beetles favour flowers with dark beetle markings over<br />unmarked flowers. 2011-06-30T14:45:24Z Manning, John C. van Kleunen, Mark 2011-06-30T14:45:24Z Donaldson, John S.
