Reproductive success of iteroparous insects depends on their own survival as well as that of their offspring and thus adults should consider risk of predation to both themselves and their offspring when selecting a suitable place to lay eggs. We surveyed species composition of Enallagma damselflies from sites in eastern Ontario and found that, similar to studies in Michigan, USA, Enallagma boreale does not co-exist with fish, whereas E. signatum is apparently restricted to sites with fish. E. ebrium is found at fish and fishless sites. Laboratory experiments on these species showed no effect of chemical cues of fish presence on propensity to oviposit or number of eggs released. By using field enclosures, we found adult E. ebrium could detect and avoid fish during visits to a site, but females visiting fish sites did not significantly reduce oviposition duration.
