| Abstract | | German | German Wiesenkerbel; Fliegen, Wespen. Der doldenartige Blütenbau ermöglicht Besuch und Pollination durch gering spezialisierte Insekten. In verschiedenen Stadien der Einzelblüten wird den Antheren Blütenstaub entnommen, bzw. dem Griffel zugeführt. | | English | English Insect activity on the umbels of Anthriscus silvestris (Cow Parsley, Umbelliferae, Apiaceae) is shown as an example of pollination of allotropous (allophilic) blossoms with open nectar, by a series of low-specialized visitors. Structure and floral stages of the single flower as well as the behaviour of insects, especially hover-flies feeding nectar and pollen, are demonstrated in detail. |
