Divergence times or earliest fossil occurrences of host plants for Aphidinae and Pterocommatinae aphids.

a: geological time scale from Gradstein and Ogg [78].b: fossil means the earliest fossil record. Dating method in parenthesis: B, relaxed-clock in BEAST; M, relaxed-clock in MULTIDIVTIME; N, non-parametric rate smoothing in R8S; P, penalized likelihood in R8S.c: range of the epoch period.d: age inferred from the higher taxon.e: inferred by phylogenetic relationships with Fuchsia and Oenothera.f: absolute age based on the earliest fossil by Lopez-Vaamonde et al. [11].
