Figure 2 in Beetles and lichens: tracing the origins and evolution of lichenophagy within the darkling beetle tribe Helopini (Coleoptera: Tenebrionidae)

Figure 2. Results of the ancestral state estimation analysis. Terminal taxa are colour-coded according to their state as illustrated in the key. Pie charts demonstrate the probability of the ancestral state at each node. In order to provide a time frame for the emergence of different ancestral modes, a time axis is also provided (based on the BEAST run calibrated by known substitution rates). A, evolution of feeding modes under the ER model. B, evolution of habitat preferences under the SYM model within the tribe Helopini.
