Studies are needed to identify relevant life-history parameters responsible for their successful spatial spread. This study is a detailed analysis of phenotypic variation in reproductive traits of several Nearctic and Palearctic populations of these two coccinellid species. From 47 to 61% of C. septempunctata females laid their first batch of eggs within the first two weeks of their adult life. Within P. quatuordecimpunctatapopulations, 56 to 83% of females initiated oviposition within 2 weeks. The remaining females either had preoviposition periods > 2 weeks or never laid eggs during a 60-day observation period. Analysis of daily fecundity revealed differences in oviposition strategies among females within each population. Repeatability estimates of daily parity for C. septempunctata populations were 0.32 for Iowa (USA), 0.35 for Delaware (USA), 0.28 for France, and 0.33 for Ukraine. Repeatability estimates for P. quatuordecimpunctata populations were 0.35 for Canada, 0.25 for France, and 0.33 for Turkey. The within-female component accounted for most of the variation in daily parity; this was due to female variability in their daily oviposition rates.
