Figure 1. Haplotype network for CO1. Circle size and line length are proportional to the haplotype frequency and the number of mutations, respectively. Geographic regions are color-coded. Numbers on the pie charts indicate the number of individuals with the particular haplotypes in the region. The wing morph is represented by the following patterns: solid, L morph; diagonal stripe, S morph; crossed stripe, wing type unknown. Black square dots represent potentially missing haplotypes. The number of short vertical lines represents the number of mutational steps. Five short vertical lines indicate more than five mutational steps.
