The carnivorous bladderworts (Utricularia) possess complicated suction traps. Remarkably, information on the prey trapped is relatively sparse. We have conducted a detailed survey on the prey spectra found in traps of selected aquatic bladderworts (U. australis, U. vulgaris) occurring in ponds in northeastern Germany. A close examination of more than 200 traps revealed cladocerans, copepods, rotiferas, ciliates and insect larvae as being common prey.Of particular interest was the considerable amount of phytoplankton (i.e. algae, cyanobacteria) found in the traps. In total, more than 160 algae species (among others, Kirchneriella lunaris, Scenedesmus quadricauda and S. acuminatus) belonging to more than 50 genera were present, with Chlorophyceae being dominant. The role of the vegetarian diet for nutrient supply of bladderworts is discussed.
