1. In the littoral zone of a mesotrophic freshwater lake (Lake Selent, Northern Germany) much higher concentrations of heptadecene‐1 were found within a swarm of Polyphemus pediculus than in lake water at some distance from the swarm. Polyphemus collected in the field produced large amounts of heptadecene‐1 when exposed to osmotic shock. Other volatile compounds were not detected. 2. Heptadecene‐1 could be involved in the formation, maintenance and recognition of swarms of Polyphemus. It is the first report of the release of a volatile organic compound from a freshwater crustacean.
