Results from ancestral state estimation of nesting habit and social parasitism in the core formicoxenines sensu Ward et al. [2], as inferred from an average of all models tested with HiSSE. Branches are painted according to transitions between arboreal (white) and terrestrial (black) nesting habitat. Pie diagrams at nodes indicate the likelihood of arboreal vs. terrestrial nesting habitat. Symbols on branches indicate transitions between states, as indicated in the key. Arrows between species indicate parasite/host relationships
