Phylogenetic optimizations on the lepidopteran baculovirus species tree. Optimizations were obtained by ancestral state estimation of (A) host Lepidoptera at superfamily level, and (B) insect host plant growth type traits on the ingroup of Lepidoptera infecting baculovirus. The term “Herb/woody” in the legend means that insect hosts feed on herbaceous plants as well as woody plants. Black circles close to phylogenetic nodes refer to posterior probabilities over 0.75. Baculovirus species denoted by black line rectangles correspond to clades that are significantly topologically congruent (p < 0.5) with lepidopteran host clades.
