Modern ecosystems display complex associations of plants–insects that underwent a long evolutionary process since the appearance mid-Paleozoic vascular plants. Although several major hypotheses explain evolution these plant–insect associations, initial pattern modern insect herbivory is poorly understood. To understand antiquity patterns terrestrial arthropod herbivory, functional feeding group–damage type (FFG-DT) data were used to analyze 305 My interval from Late Pennsylvanian present, in which 134 plant assemblages assess turnover (replacement some species by other between sites) and nestedness (difference composition when no are replaced pairwise comparisons DTs. Results beta diversity analyses indicate prototype for was established on gymnosperm-dominated late Middle Jurassic, antedating angiosperm dominance 60 My. Turnover among groups FFGs declined earlier Paleozoic, whereas during later Cenozoic, generally increased. Insect gymnosperms showed one change with low high nestedness, bimodal characterized angiosperms. Ferns angiosperms exhibited less DT breadth (host-plant “specificity” herbivores) than gymnosperms, reflecting differences links herbivores their host This fundamental trophic shift consistent Mid-Mesozoic Parasitoid Revolution, implying top–down control consumers rather bottom–up regulation food sources shaped pattern. These findings provide data-rich account ecological origins herbivory.

Abstract Rhus gall aphids (Hemiptera: Aphididae: Eriosomatinae: Fordini) are obligate parasites that only use species (Anacardiaceae) as their primary host plants, and each aphid feeds specifically on one or two sister species. Both hosts exhibit the same disjunct distribution pattern between East Asia eastern North America. We assembled complete mitochondrial genomes universal single‐copy nuclear genes for using a genome skimming method estimated phylogeny from dataset. Results strongly supported monophyly of Fordini genera, Floraphis Melaphis . However, relationships among genera were inconsistent different datasets. also plants published chloroplast genomes. The Dating analyses suggest most recent common ancestor was much older than plants. divergence times some species, particularly those with more times, consistent ages corresponding This may established an initial association stem‐group ancestors Anacardiaceae acquired extant they evolved through switching another plant group. Divergence time estimates implied separation America Eurasia Laurasia supercontinent subsequent disappearance Bering Land Bridge, respectively, have played important role in American Asian lineage. Our results provide new insights into coevolution insects
