Fig. 4From: Maternal care in Acanthosomatinae (Insecta: Heteroptera: Acanthosomatidae)—correlated evolution with morphological changeLikelihood reconstruction of ancestral state of egg-guarding behaviour (left) and Pendergrast’s organ (right) in 34 terminal taxa without missing data. Values on the nodes of interest were shown, and indicate proportional likelihood. The states judged best estimate under the threshold (2) are marked with an asteriskBack to article page
