Occurrence of copulation in N. vitripennis depending on origin of mating partners. A Females and males originate from the same strain (green), or from different strains but the same microsatellite cluster with k = 3 (yellow) or k = 5 (orange) subpopulations, or the same microhabitat (blue). B Females and males originate from different strains but the same microsatellite cluster with k = 3 (yellow) or k = 5 (orange), or from different microsatellite clusters (yellow/orange), or originate from the same (blue) or different microhabitats (white/blue). Coloured parts of the bar indicate the percentage of couples with copulation. Numbers in bars indicate numbers of replicates. Different letters above bars in A indicate significant differences at p < 0.01 (Tukey-test based on a generalized linear model, family “binomial”). In B, ANOVA was based on a generalized linear model, family “binomial”
