Predation and potential transfer of pollen in a population of Saxifraga hirculus
Body surface pollen load and gut pollen (pollen diet load) of flower visitors in a Danish population of Saxifraga hirculus were analyzed. The four most frequent visitors, Eurimyia lineata (Syrphidae), Neoascia tenur (Syrphidae), Asindulum nigrum (Mycetophilidae), and Zygaena trifolii (Zygaenidae) ha...
