Phylogenomics resolves the timing and pattern of insect evolution
The phylogeny of all major insect lineages reveals how and when insects diversified and provides a comprehensive reliable scaffold for future comparative analyses of evolutionary innovations among insects.

It is found that the abundance of amber during the Carnian is globally anomalous for the pre-Cretaceous and may, alternatively, be related to paleoclimate.
An integrative phylogenomic approach illuminates the evolutionary history of cockroaches and termites (Blattodea)
The first nuclear phylogenomic study of termites and cockroaches with a thorough approach to divergence time analysis, identification of endosymbionts, and reconstruction of ancestral morphological traits and behaviour shows that most subgroups of Blattodea evolved in the Cretaceous.
The earliest known holometabolous insects
Although these discoveries reveal unexpected Pennsylvanian eumetabolan diversity, the lineage radiated more successfully only after the mass extinctions at the end of the Permian period, giving rise to the familiar crown groups of their respective clades.
Debris-carrying camouflage among diverse lineages of Cretaceous insects
It is demonstrated that the behavioral repertoire, which is associated with considerable morphological adaptations, was already widespread among insects by at least the Mid-Cretaceous, and is provided a novel insight into early evolution of camouflage in insects and ancient ecological associations among plants and insects.
THE MIDDLE EOCENE BEE FAUNAS OF ECKFELD AND MESSEL, GERMANY (HYMENOPTERA: APOIDEA)
The bee fauna is compared with that of the contemporaneous Baltic amber and it is concluded that the majority of bee specimens are from the advanced eusocial lineages of the corbiculate Apinae.
Ancient death-grip leaf scars reveal ant–fungal parasitism
This work documents the first example of the stereotypical death grip from 48 Ma leaves of Messel, Germany, indicating the antiquity of this behaviour and support a biogeographical parallelism between mid Eocene northern Europe and recent southeast Asia.
No post-Cretaceous ecosystem depression in European forests? Rich insect-feeding damage on diverse middle Palaeocene plants, Menat, France

The results show that the end-Cretaceous event did not cause a uniform, long-lasting depression of global terrestrial ecosystems, Rather, it gave rise to varying regional patterns of ecological collapse and recovery that appear to have been strongly influenced by distance from the Chicxulub structure.
