Relationships among the 9 sampled Leucorrhinia dubia populations across Europe based on 1674 SNPs from ddRAD sequence data.

Thin lines represent densities that represent the branches. Alternative topologies are drawn in different color, where blue represent the most supportive, followed by red and green. The triangles to the right represent cartoons of larval spine length showing the proportional differences in length. Note that in reality the longest spines are also wider at the base.
