Abstract

Predatory invertebrates play a significant role in the organisation of aquatic communities. However, their ecology is poorly known even for many common taxa. We examined the meso-habitat use and aspects of movement activity of two common predatory water bug species Ilyocoris cimicoides (L., 1758) and Nepa cinerea L., 1758 under field and laboratory conditions in order to assess the effect of the patchiness on habitat choice. Ilyocoris cimicoides preferred open habitats, rich in submerged vegetation, without submerged terrestrial materials. Shaded habitats such as under trees, with moderately dense vegetation and submerged branches, were favoured by N. cinerea. Both laboratory and field data indicated differences in the short-term and similarity in the long-term movement behaviour of the two species. In the short-term, I. cimicoides moved frequently, while N. cinerea moved rarely, but the distance visited over the course of a longer time span is comparable.
