Evolution of morphological parameters of Ae. japonicus eggs throughout the year. Figure 5A: length; Figure 5B: width; Figure 5C: volume, data of 2019. Figure 5D: length; Figure 5E: width; Figure 5F: volume, data of 2020. Data come from the Reichstett field area. Eggs are batched according to the calendar week of collection. Corresponding months and seasons in coloured horizontal bars are also shown (green = spring, yellow = summer, orange = autumn). Boxplots of corresponding weeks considered for the linear regression are shown in grey. In Figures 5B and 5C for 2019, linear regressions in solid black lines ignore data point of weeks 20, 22, 24 and 45 as well, which are shown in a white boxplot. For 2020, data for weeks 20–25 are discarded.
