Reconciling field results with the laboratory experiments on size-dependent mating initiation success. (a) The correlation between FTG and MCG in mating pairs of G. gracilicornis in a field population (Gwanak, Seoul). Y = 0.8188X + 0.1032, r² = 0.158, P = 0.003. (b) Distribution of regression coefficients from the computer simulation using mating initiation success rates based on the laboratory data (see inset, and Figure 3B). 95% confidence interval for the simulated distribution of the regression coefficients is between 0.685 and 0.989. The arrow indicates the regression coefficient between FTG and MCG in mating pairs of G. gracilicornis in a field population.
