The evolution of insect metamorphosis is one of the most important sagas in animal history,
transforming small, obscure soil arthropods into a dominant terrestrial group that has …

Arthropods are the most diverse animal phylum, and their phylogenetic relationships have
been debated for centuries. With the advent of molecular phylogenetics, arthropods were …

Phylogenetic relationships among subgroups of cockroaches and termites are still matters of
debate. Their divergence times and major phenotypic transitions during evolution are also …

Insects comprise over half of all described animal species. Together with the Protura
(coneheads), Collembola (springtails) and Diplura (two-pronged bristletails), insects form …

Background Arthropods comprise the largest and most diverse phylum on Earth and play
vital roles in nearly every ecosystem. Their diversity stems in part from variations on a …

Communication by substrate-borne mechanical waves is widespread in insects. The
specifics of vibrational communication are related to heterogeneous natural substrates that …

Most organisms possess time-keeping devices called circadian clocks. At the molecular
level, circadian clocks consist of transcription–translation feedback loops (TTFLs). Although …

Phasmatodea comprises over 3,000 extant species and stands out as one of the last
remaining insect orders for which a robust, higher-level phylogenetic hypothesis is lacking …

The insect order Psocodea is a diverse lineage comprising both parasitic (Phthiraptera) and
nonparasitic members (Psocoptera). The extreme age and ecological diversity of the group …

Insects constitute the most species-rich radiation of metazoa, a success that is due to the
evolution of active flight. Unlike pterosaurs, birds and bats, the wings of insects did not …
