The effect of harmonic convergence across body size combinations. Proportion of copulas formed by converging (blue, square) and non-converging (red, circle) of different body sizes in live pair interactions. (n = 266 pairs). a Copulas involving small females. The presence of a convergence event increased the probability of copula formation for males of both body sizes. (n = 117 pairs). b Copulas involving large females. An interaction between male size and presence of harmonic convergence increased the likelihood of male mating success when approaching large females (n = 149 pairs). Error bars represent ± 2 standard errors (SE)
