FIGURES 152‒153. Reconstruction of ancestral states by parsimony in Mesquite for two colour-pattern characters each with two states among species based on the estimate of phylogeny in Fig. 138, several of which are polymorphic and show both states for both characters (re-drawn from Williams et al. 2015): (152) banding colour pattern, with yellow spots showing yellow-banded (B) populations (minimally with yellow hair clearly visible anteriorly on the thoracic dorsum), black spots showing unbanded (U) populations, mixed yellow/black spots showing polymorphic populations, mixed yellow/grey spots showing uncertain polymorphic/monomorphic populations (*for B. alpinus, males from the Alps often have a yellow-banded pattern although this is rare among females); (153) tail colour pattern, with orange spots showing populations with pale (P: orange or white) hair on the tail (minimally with orange, yellow, or while hair clearly visible on metasomal tergum 5), black spots showing populations with dark (D: black) hair on the tail, mixed orange/black spots showing polymorphic populations.
