Figure 5 in Mimetic colour pattern evolution in the highly polymorphic Bombus trifasciatus (Hymenoptera: Apidae) species complex and its comimics

Figure 5. Per cent darkness of wings across the distribution of Bombus trifasciatus, Bombus breviceps, and Bombus haemorrhoidalis lineages. In B. trifasciatus two hierarchical levels of relationship are outlined: solid lines represent the major coloured sublineages inferred in Figure 6, and dashed lines represent higher-level bifurcations supported by mitochondrial, nuclear, and some morphometric data. The question mark indicates Bombus trifasciatus magrettianus, which has uncertain sublineage affinity.
