Distribution of EF-1α haplotypes among populations of Maculinea arion sampled in Italy and Poland. The data are supplemented by haplotypes detected by Als et al.  and the maximum parsimony networks for all haplotypes. Rare EF-1α haplotypes (present only in one or two populations) are left uncoloured. The sizes of the circles are directly proportional to the number of individuals analysed. For full site names and other details see Table 1.
