✦ Synopsis

The food of lake-dwelling Erpobdella octoculata, Glossiphonia complanata and Helobdella stagnalis was determined by exposing potential prey organisms to leech attack in dishes, in the laboratory . For each prey species, four experimental regimes were used ; these contained prey and leeches of different sizes .

E. octoculata fed extensively on chironomids and oligochaetes, G . complanata on gastropods, oligochaetes and chironomids, and H. stagnalis on a wide variety of prey, including oligochaetes, chironomids, gastropods, Asellus and mayflies . Feeding was most intense during periods of darkness . Findings are compared with those of previous studies .

Prey species show specific adaptations that allow recognition, avoidance and defense against predators. For many mammalian species this includes sensitivity towards predator-derived odors. The typical sources of such odors include predator skin and fur, urine, feces and anal gland secretions. Avoida

## Abstract The predatory impact of __Chaoborus flavicans__ on zooplankton, especially on daphniids, is often regarded as a crucial factor in the propagation or repeal of top‐down effects in lakes. Therefore consumption rates and prey selectivity of __C. flavicans__ were determined in mesotrophic L
