Figure 2. Estimation of divergence time between the S morph and the ancestral L morph haplotypes based on Bayesian inference using COI. Wing morph, country identity, and Wolbachia infection status are displayed: L = long-winged, S = short-winged, u = unknown, K = Korea, J = Japan, U = USA, W = Wolbachia . For clarity, all other node error bars representing 95% HPD are removed, except those for the nodes of the two clades and the occurrence of the S morph haplotype.
