Ants are a dominant family of eusocial terrestrial insects with a diversity of ecologies,
lifestyles and morphologies. Ant diet preferences range from strict carnivory through …

Recent progress in beetle palaeontology has incited us to re‐address the evolutionary
history of the group. The Permian† Tshekardocoleidae had elytra that covered the posterior …

Insects evolved various modifications to their mouthparts, allowing for a broad exploration of
feeding modes. In ants, workers perform non-reproductive tasks like excavation, food …

Insects use their mandibles for a variety of tasks, including food processing, material
transport, nest building, brood care, and fighting. Despite this functional diversity, mandible …

Fossils provide unique opportunity to understand the tempo and mode of evolution and are
essential for modeling the history of lineage diversification. Here, we interrogate the …

Abstract Tatuidris tatusia Brown & Kempf, 1968, the armadillo ant, is a morphologically
unique species found in low to high elevation forests in regions of Central and South …

Advanced social behavior, or eusociality, has been evolutionarily profound, allowing
colonies of ants, termites, social wasps, and bees to dominate competitively over solitary …

The correct interpretation of fossils and their reliable taxonomic placements are fundamental
for understanding the evolutionary history of biodiversity. Amber inclusions often preserve …

For social insects such as ants, the internal organs are likely important in understanding
their eusocial behavior and evolution. Such organs, however, are rarely preserved on …

The male genitalia of the Insecta are famed for structural and functional diversity. Variation in
this anatomical region shows ample phylogenetic signal, and this variation has proven …
