    Predatory aquatic insects are a diverse group comprising top predators in small fishless water bodies. Knowledge of their diet composition is fragmentary, which hinders the understanding of mechanisms maintaining their high local diversity and of their impacts on local food web structure and dynamics. We conducted multiple-choice predation experiments using nine common species of predatory aquatic insects, including adult and larval Coleoptera, adult Heteroptera and larval Odonata, and complemented them with literature survey of similar experiments. Our results show that all predatory species are more or less selective. We identify separate modules in the experimentally assembled food web and demonstrate that ontogenetic diet shifts might be less pronounced in these predators than in other groups.
