Cladogenesis of the main insect groups in a chronological context. The phylogenetic reconstruction is based on Misof et al. [11] and Wang et al. [12]. The main discrepancy between these two proposals is the situation of Paraneoptera, which is monophyletic for Wang et al. and polyphyletic for Misof et al. Divergence times are generally similar in both proposals. Those indicated here are based on the average values reported by Wang et al. [12]. Modified from [12]. (Online version in colour.)
